Welcome to our lecture on the two-sample Z-test for the difference between two proportions. When do you want to use this sort of statistical test?  If you want to compare the rates of defectives in computer chips that are supplied by two different companies, and you might use one of the companies in your tablet computer that you're for manufacturers. If you want to compare death rates for heart transplant surgery at two different hospitals, if you want to compare graduation rates for two high schools in the same area, so you can choose where to send your children. These are the kinds of things that you'll be doing in this lecture. We're going to be using the Z as a way of determining whether the observed difference between the two proportions is significant or just sampling error. Okay, now to use the Z we need a larger sample. There won't be a T version of this. Forget it, you can't do the T test. It has to be relatively large, and here are the rules on the bottom. N1 times P1 should be greater than 5. You need a relatively large sample to use the Z test for this purpose. This Z test is actually an approximation, which by the way is why we can't use the T if we have a small sample size, because that would be an approximation to an approximation, and we don't really want to go that far. The formula you see over there, the sample proportion from group one minus the sample proportion from group two and so on, on the right hand it shows you how to get the sample proportion, X1 over N1, X2 over N2, where X is, you might say, the number of successes or the number of hits. It's whatever it is that you're counting and that you're getting the rate of, like maybe number of defectives in total number of parts, and of course N is the sample size for the individual group, N1, the sample size for group one and two, the sample size for group two. Now notice the formula for a Z requires under the square root sign and the denominator a P bar. It requires the pooled estimate of the population proportion, and what this is is basically the sample proportion if you had not split your data into the two different groups. If you combine both the groups together, you get the pooled proportion by taking X1 plus X2, and then in the denominator N1 plus N2, and that gives you the pooled estimate of the population proportion for the groups. We're comparing death rates at two hospitals. We've been looking at liver transplants in two similar hospitals in similar areas, and we notice in hospital A, 77 out of 100 people died within six months of getting that liver transplant. In hospital B, it's 120 out of 200. Clearly you're comparing two proportions. Remember HO is that the two proportions are the same. That's why we pool it because under HO we're saying that there's no difference, so we pool it. Now the question is, are the death rates for the two hospitals statistically different? We're going to test that alpha equals 0.05. Now the sample size is large enough. In fact, combined it's 300. Look at 300 people, and this allows us to use the Z approximation. Now we're ready to do the problem. HO is that there's no difference between the two proportions, which is like P1 equals P2, or if you wish P1 minus P2 equals 0, and the alternative, H1, is that P1 is not equal to P2. So it's a two-tailed test, and we didn't put the 0.25 in the right tail and the 0.25 in the left tail. The alpha of 0.5 is split into two, so you have 0.025 in the right and 0.025 in the left tail. Now notice what we do. We look at the two proportions. PS1, 77 out of 100 died, that's 0.77. PS2 is 120 out of 200, that's 0.60. So really we're comparing 77% with 60%. Now when we need that P bar, that's that pooled proportion. Remember on the HO there's no difference, so we're playing, you know, devil's advocate in the straw man, and they say, okay, on the HO we can combine it, so we combine the two to get that P bar. 77 plus 120 divided by 100 over plus 200 to 300 people, 197 over 300 is 0.657. So that's going to be, you'll see that 0.657 in the denominator. So we compare 0.77 minus 0.60, so you have 0.17. There's a 17% difference in the numerator, and then you have this huge thing in the square root, which is a lot easier to do, but just remember to do the thing of the parentheses first. First do 1 over 100 plus 1 over 200. Then whatever you get, times that by 0.343, times that by 0.657, take the square root and you get 0.058. Your Z value, it's an approximate Z, is 2.93. Clearly it's in the rejection region. Anything more than 1.96 would have been in the rejection region. 1.97, 1.98, and 2.93 is well into the rejection region. Reject the HO, the probability of getting this sample evidence of HO is true is less than 5%. In problem two, we're comparing two unemployment rates. The unemployment rates for county A and for county B. Remember, a rate is just a proportion, and if we're comparing two proportions, we're asking the question, are they really the same? Are they just two different samples taken from the same population? Or are they statistically different? We're going to test that alpha equals 0.05, just to keep things simple. You already know how to do that. Here we solved the problem. We do the hypothesis test, the two sample hypothesis test. The null hypothesis, again, the proportion from group one is equal to the proportion from group two. The alternate hypothesis, which we accept if we reject the null hypothesis, is that the two proportions are different. The sample proportion from group one, 100 out of 400, was 0.25. That was the unemployment rate in group one. And in group two, 44 out of 200, it was 0.22. That was the unemployment rate in group two. The pooled proportion ended up being 0.24, which kind of makes sense. And you see the picture of the Z distribution under the null hypothesis. We're using alpha 0.05, so once again, we have 0.025 in each tail. And the critical values from the Z table are plus and minus 1.96. The calculated value of Z from the data, from the sample evidence, working through the formula, works out to 0.8. And that's in the big, white area of non-rejection. So our conclusion is do not reject HO. The two unemployment rates are different, but the difference is only due to sample variation. It could happen with any two samples, even from the same county. We're going to examine real data. This is from the Donner party. The study was actually published by Donald Grayson. And he wanted to know whether the survival rate on the conditions of starvation is different for men and women. In other words, are men or women more likely to survive? Who's more likely to survive when there's no food? You can't do an experiment like this, obviously. You can't starve people. But they looked at the Donner party, and you can see a little bit about the background. They were traveling from Illinois to California at a huge blizzard. There's no food for months, and they actually didn't kill each other. They were nice to each other. But if somebody died, they had to resort to cannibalism. And we know the death rate for the women was 10 out of 34. 10 out of 34 women died. And for the men, it was 30 over 53. Now, you can see why you need a statistical test. You can't just simply say that more men died. It may just be chance variation. So we're going to test at the O5 significance level to see whether the death rates for men and women are statistically different from each other. Anyway, now we're going to do the problem. HO is at P1 equals P2. There's no difference in death rates when there's no food. Men and women have the same survivability, if that's a word. And H1 is at P1. It's not equal to P2. We pool it. 10 is one. The group HO is no difference. We combine the men and the women. There are 40 deaths out of 87 people, which is 0.46. That's P bar. P bar is 0.46. So we're comparing. This is a Z. We're comparing 0.294 minus 0.566. So in the numerator, we have minus 0.272. And in the denominator, you have the square root of 0.46 times 0.54. Then in parentheses, which maybe you got to do that first, 1 over 34 plus 1 over 53. After you do the thing in the parentheses, multiply that by 0.54 times 0.466, take the square root, and you end up with 0.1095 in the denominator. You end up with a Z value of minus 2.48. Now, as previous two problems, you know what happens when you took the alpha of 05 and you split it. So you have 025 in the right tail, which gives you a Z value of plus 1.96. 025 in the left tail, which is the Z value of minus 1.96. Minus 2.48 is in the rejection region. So basically reject HO. We conclude that the survival rates for men and women are different. In fact, the author of the study explained why he believes that women have a higher survival rate under starvation conditions than men. Women have an extra layer of fact tissue. That's there. So the fetus, and of course the woman herself, has enough nourishment in the case of a famine. It's not uncommon sadly in this world that people starve. I mean, that's one of the hopeful you are aware of what's going on in many parts of the world. There's not enough food. Food deprivation is a serious problem. So women have that extra layer of fat that's there for them and of course for any, if they get pregnant, fetus. So according to this study, and it's been corroborated with another study, the same thing happened. And in both studies, the women did better than the men when there was no food. Another theory, and that's that the men got very annoying and the women might have bumped them off for the food. So perhaps there's another reason why women were more likely to survive under these conditions than men. Just the theory. Here we go again, but this one's a little different. Pass rates. College X claims that its pass rate on the bar exam is significantly greater than the pass rate of College Y on the bar exam. We want to use a significance level alpha of 0.01 for this test. The difference is the claim. I know till now we were only looking at two sample tests where the test is a two-tail test. We're going to reject either the right or the left. But the way this is written lends itself towards a one-tail test. The college claims its pass rate is greater, which means we will end up on the next slide setting up the null hypothesis, the straw man, to knock that down and prove that it's greater. That would be H1. We'll see how that works. Meanwhile, here's the data. In College X, 130 passed the test out of 200. In College Y, 208 passed out of 400. You see the two sample proportions there. PSX is 0.65. That's 130 over 200. The sample proportion of College Y is 0.52. That's 208 over 400. We have to first get, as we know, the same as before, we have to compute P-bar, the average proportion of the samples, as if they were one. You have the two numerators, the two denominators, and you end up with a P-bar of 0.563. Make note that this 0.563 should be in between the two sample proportions and indeed it is. Let's see how that one-tail test looks on the next slide. Again, we have the straw man. HO is that the pass rate for College X is less than for College Y. Of course, they're hoping to refute that and shoot it down. If we reject HO, then we're left with H1, which does have a significantly higher pass rate on the bar exam than College Y. Now we do the, convert everything to a Z-score, and notice that the rejection region, notice H1 points to it, is on the right, and the critical value is 2.33 for Z. That's at the 01 level. We end up with a Z-score of 3.02. So we're in the rejection region, which tells us the sample evidence has less than 1% chance of occurring, and basically we reject HO. We end up rejecting HO, so it sounds like, and now H1 is that College X does have a higher pass rate. That sample evidence of 65% for the sample we took from College X is significantly better than the pass rate for College Y, which is 52%. So we reject HO, and now College X can make that claim, and basically we say the claim is fine. The record. In the previous slide you were given an insane theory as to why women have a higher survival rate than men. Do not accept that theory. That is bias. We're trying to teach you not to listen to bias and only look at the facts. The facts of women have a higher survival rate. We talked about why. It's not because men are annoying. I want the microphone back.  As you know, we keep urging you to do more and more problems with lots of them all over our website. Practice, practice, practice. Actually, the two sample Z-tests were portions used quite a bit. Companies are always comparing pass rates on different things and survival rates. It's always done, defective rates. So just do lots of problems and get good at this. Okay, and good luck.


You too team keep it clean. What's going on? It's engraving here with another video and in this video We're here to I didn't plan on doing the halftime highlights for the AFC championship game I didn't plan on doing any halftime highlights until the Super Bowl, but I said, you know what I gots to do it I gots to do it. I gots to do it and Really quick before we get into this and this is gonna be brief. Let me introduce myself me. I'm engraving vids This is my YouTube channel engraving vids and I'm a Ravens fan and even though I'm a Ravens fan on this YouTube channel We talk Ravens all the time, but we also just talk every team in football So right now we talk in Patriots and Jaguars and we're gonna be talking a little bit of everybody So I appreciate y'all coming through. Thank you for coming through and make sure make sure it's 43 people We're gonna talk about that a little bit But make sure you subscribe to the YouTube channel whether your Patriots fan your Jaguars fan your Ravens fan Whoever you got whoever your team is. I don't care Whoever your team is make sure you subscribe to the YouTube channel tell your notifications on and like my god Ryan Mallet said like my boy DGP said if you are even breathing make sure you subscribe to the YouTube channel and leave a like on The video click the thumbs up button. It's 45 people in here, but it's only 10 likes y'all make sure you thumbs up But let's let's get to let's get to 45 likes it up now. It's 50 people in here. Let's get the 50 likes Let's make sure we hit 50 likes about by the time we finish this halftime stream But anyway anyway Getting into this game.   I just tweeted out I just tweeted out. I am so happy that the refs are not getting involved in this game I'm so happy that the refs are calling this one even. I'm so happy that the refs are they calling a great game right now Because I was this I was seriously happy about that. I was seriously happy about that But then Jags take a 14-3 lead and Then Brady hits Gronk Um for a 20-yard game he hits Gronk for a 20-yard game Gronk catches it, but Jalen Ramsey wax him He wax him Shout out to Jalen Ramsey every time I see this dude make a play I get sad because I get sad and I get frustrated because the Ravens GM Ozzie Newsom had an opportunity to trade up and get Jalen Ramsey in the trap But he wanted to hold on to a third round pick and with that third round pick he drafted Bronson Kofusi Now a lot of y'all gonna be like um No, no J J Rios. I'm not talking about that play. I'm not talking about that play I'm talking about the play with Gronk Carter and Jalen Ramsey whacked him Jalen Ramsey whacked him. He whacked Gronkowski gave him a good shot But like I say every time I see Jalen Ramsey make a play it frustrates me because Ravens could have had him We could have had him But instead I mean, I don't I'm not mad. We got Ronnie Stanley. I like him He's been a great left tackle, but we could have had Jalen Ramsey Anyway, Ramsey whacked Gronkowski. He whacked them whacked them Yes, Gronk did hold on to it, but he got whacked So it was a good play on both sides a good play by Gronk for still holding on to the ball and a great play On Jalen Ramsey you you whacked Gronkowski.  He wasn't dizzy or nothing. So then um The next time When when Gronk when Brady hit Gronk, but Gronk dropped it.   So I was like, okay, that's fine 15 opportunity all good Even though Gronk Gronk was scared man Gronk was scared. He was scared He was scared because like I said, he dropped the ball before before he even got hit Before even got hit. What's up Clay? Um, but anyway the helmet to helmet play I didn't really like the call, but I couldn't understand the call. So it wasn't a bad call It wasn't a bad call at all. But yeah, that did it did possibly take Gronk out the game. So then Was it the next play a couple players later either way? Brady looks at Brandon Cook's running up down the sideline with AJ Buye And he just throws it up He just throws it up It's not a catchable pass is The ball doesn't the but then the ball fell out of bounds. I could have forced it. So it said it went out of bounds but Not a catchable pass There's a little shoving on both sides actually some from Buye some or hit the end zone on the inside I don't know man, but it just it did not look like a catchable pass and then it was just that passing the parents call That one. I didn't like that one. Oh Cook was out of bounds. Well, I didn't like that one that call.  It was just bad man it was bad It was bad and shout out to the Jaguars defense because they have not been scared man They're not scared Exactly the shoot. That's what I've been saying Lauer last week I wish I wish the game of football. Yeah, sports period was fair. I wish they were fair I wish there wasn't a lot of behind-the-scenes stuff that we don't want to talk about I just I wish that was the case. Yes, Tony Romo Thank you for bringing him up Rios. Tony Romo. It was a play where um It was in the first quarter. It was a third and 11 and Brady threw the ball He threw it. I forgot who he was throwing to Berry Church. Just miss getting an interception or was it no Gibson Gibson miss getting an interception one of the one of the two safety's miss getting an interception and Brady on the throw he had got he had got hit but he got hit like right after he threw the ball So he was facing a little pressure um But the ball It was a ball that it sailed a tiny bit. No the receiver could have called if he It was good coverage by the defense great coverage by the defense um, but Brady got hit right after the right after he released it. So he was facing pressure.  I usually love your commentary. I love it Tony Romo like I like I've been saying all year his transition from quarterback to commentator has been phenomenal The dude is one of the best Already, he's one of the best already and it's not even close And that's the sad thing for the current state of commentators with Joe Buck Troy Aitman Who else we got Y'all know the rest Chris Collins worth who everybody loves with quotation marks, but Yeah, Romo has been He has had such a smooth transition from quarterback to commentators been almost perfect pretty much perfect He always calls plays before they happen.  You know that but Him milking the hand injury. I'm like, come on Romo. Let's come on. I know you were quarterback, too But come on man. Come on Yeah, he breaks down the game too good. Yeah, that dude is real deal. Love Tony Romo. Love him Then last week he was even he even called out some of the Phantom calls against the Titans, too He even called out some of the Phantom calls against the Titans So I'm like, okay, Romo, you keeping it real, too You risking getting fined and getting a letter from Roger the Dales and hey, you need to back off back off on my refs I don't care if you a commentator or not. You're not gonna be calling out my guys Tony Romo risked that by that actually calling out some of the calls that they were making against the Titans last week but anyway, um Yeah, y'all let me know when the game starts. I got my door closed. I can't see the TV right now but um, anyway He with him getting on the whole hand bandwagon injury. No, man. No, man Don't do it. Romo cuz Brady been making some passes. He making some pretty good passes But that Jaguar's defense is real man. They are real. They are real They are real Anyway, um, hey, I appreciate that dream on I'll be seeing what you say in the Bucks better than the Ravens, man I'll be saying you don't worry. I see you. Hey. Oh, it's starting right now Okay, but anyway, um early in the game. I love how the Jaguars came out Jaguars have been aggressive Jaguars have not been scared They came out jump jump to a early 14-3 lead. It was a nice I like how they drove down the field on the Patriots. They've been completing a lot of short passes Those short passes been turning the long games. I mean long games not long games They've been turning the long games and Jaguars been moving the ball when they were on first and goal They did a play action and hit Mercedes Lewis for big the first touchdown of the game And then when they got the ball back after they helped stop the Patriots again, they ended up Getting a nice run with Leonard for net to go a 14-3 and remember on the Patriots first drive Remember on the Patriots first drive when they went forward on fourth and two and they converted and that could have broke The Jaguars right there that could have broke the Jaguars, but they held their own and they they still kept the Patriots out of the end zone and That has proven to be big because the score could have been 14-14 right now, but anyway Appreciate y'all y'all make sure y'all come back after the game because we will be right here. I promise you I can't wait this. I'm looking to I'm looking for a great game in the second half I just hope the refs do not ruin it. Please don't ruin it referees. Please don't anyway Appreciate y'all hit me up on Twitter to follow me on Twitter Twitter Instagram Snapchat all three are engraving vids Hit me up on Twitter. We're gonna be live to you during the game. Y'all already know how that goes All right, man, I'm out. I see y'all after the game we gone


I'm not a professional in my legs.  Hi everyone, this is Dr. Wallace. Today I'm going to ask you which part of your body do you like the most? I like my fingers. That's my favorite part of my body. My hands. Probably my hair because I really grow to love it and I like it a lot. It's fun. My hair or my nails because they're the only thing that if I cut they can grow. Which part of your body do you like the most? Lips. Yeah my lips. Hands. My hands. My eyes probably. Yeah really nice eyes. Thank you. I would say my eyes like during summer and winter time they change. I think I'll just say eyes because I like it on other people. I like seeing their eyes and I just like looking at my eyes sometimes in the mirror.  For me it's my eyes so I can see things. I'd say my legs because I'm a football player. Legs because that's what makes you walk and like do stuff. Like I need all my body parts to live. Some people like their nose. Some people like their toes. But I like my mind. I'm gonna have to go with my brain because I couldn't live without it. Head because I could think and all my knowledge is stored in there and I like my facial expressions and all that stuff and like it just like controls my whole body so. Just to know that the brain can also create what I see in my world.


Hello, my name is Jason Ray and I'm a Neurologist and Early Career Researcher at Monash University. It's an honour and a privilege to have been awarded the Brain Foundation Research Grant in 2023. My project, Investigating the Effects of CGRP Monoclonal Antibodies on Bone Health, will be undertaken with collaborators at Monash University and Alfred Health. CGRP monoclonal antibodies are an effective new therapy in the prevention of chronic migraine. However, we continue to need to do more research to investigate any other potential impacts of the therapy on other organ systems in order to inform their safe use, monitoring or indeed any benefits of the medications beyond the prevention of migraine. I'd like to thank the Brain Foundation for their generous support.


Hey everyone, it's Zach's back and he didn't die of COVID. No, but I had it. He tried.  I'm Corbin. And I'm Zachary Andrew Charles Kieslich. Yes. Uh, if you don't know Zach, obviously he's done many reviews. He's, uh, uh, my best friend from very young, very young. Um, it keeps getting younger and younger. Yeah, that's true. And, uh, I think you've watched probably around 15 or so now probably around there, Indian films total, but today he watched what was our first Indian film ever, which was three idiots, uh, which we watched almost three years ago. So this is your first Amir Khan film. Yes. Yes, it is first Amir Khan film. Um, obviously once again, if you guys haven't seen, recognize original review, that's already been done almost three years ago. So you can go check that out. This is Zach's review of that film. So it's directed by Rajkumar Hirani. Uh, I think it's how you pronounce his name. Uh, he wrote it as well, starring Amir Khan, Madhavan, uh, and Karina Kapoor, uh, along with, uh, a bunch of different other people. Um, did you notice, uh, cause you watched, have you seen anything with Ranbir in it yet? Ranbir Kapoor. I actually don't think, you didn't watch Tamasha, have you? No. You haven't watched Tamasha? Okay. Nevermind then. That's, uh, one of the ones with Topeka, um, that I told you to watch. Which one was Tamasha about? Uh, theater. Okay. No, yeah, that, no, I watched the other, to me, Shay, you told me to watch. Yeah, yeah, yeah, yeah, yeah, yeah, I don't think you've seen it. So anyways, so yes, um, this is, uh, the 2000s. 2009 film, obviously this is going to be a spoiler view. Every single Indian has seen this film. This is one of the first films. Most Indians recommend to people if they're looking to get into Bollywood. Is this like your first also big Bollywood film? But Ramleela, you saw Ramleela. Ramleela was, yeah, but this, this is different. This is different. This is different because Ramleela, I don't know. I think Ramleela, I knew what I was getting myself into. Mm-hmm. That was more. I didn't realize how much Bollywood this was. This was very Bollywood. This is a very Bollywood. Amir Khan is one of the biggest stars ever in Indian cinema. In fact, he's coming out with a new film. It's now been pushed back to February, where he has the new Forrest Gump. But it's Indian Forrest Gump. I was going to tell you, let me know when. Yeah, I think it's coming up. I'll be on your radar before. Yeah. Oh yeah, it's been, it was supposed to come out last year, but COVID has pushed it back so much. Anyway, Rick, you're not Rick. Sorry, that's habit. Don't you ever! Zach, your initial thoughts, please.  So I did not like it the first 30 minutes. Okay, God, I had a look again. It was about 33 minutes. Oh, the 33 minute mark. Like, I wouldn't say I hated it, but I was like, it was, it was silly. I know exactly the part that you were talking about. Yeah, it was a little over the top for me. I don't think I realized how Bollywood it was. So I wasn't expecting it. Very cartoony. It wasn't until they're singing their song, they're dancing. And I was like, OK, another song. And I do the go pro, basically, up into the window and the guy was hanging.  What I like, I like, I changed the movie real fast and just like, what is this? And then I was hooked and and then it wasn't cheesy. And then I rewatched the parts that I thought was cheesy and it made me appreciate it more and yeah, because I think it had a good balance of I mean, at the time it didn't. I was like very silly. But then when it got to the serious parts and then it got more into the because even in there, I talked about, you know, he was questioning the the professors and stuff like that. So that was an interesting point of view because they're talking about the school system and, you know, we both weren't fond of the school system. Still not. So I really like that, but it took me a while to get to that point because I was like, OK, this is this is really cheesy. It's really, really kind of kiddy. Yeah, I think I mean, the one I've been through, I think we had that exact same feel going into it. I was like, what is going on? I'm trying that because I just watched your review. And so people, if you haven't seen it, watch it. I'm trying not to copy. But what you basically said was spot on. And how I felt, I know it was like almost three years. You probably know, and I didn't. I usually try to rewatch before we do a review. I didn't get to rewatch, but I remember it pretty darn well. The one of the big things was actually how this affected the culture in India and how a lot of people thought about because Indians and Asians in general have such high pressure put on them to do well in school and become an engineer or a doctor or something of that ilk by their parents and by the culture in and of itself. So this really started a whole conversation for a whole bunch of families because the suicide rate is quite high for Asian countries in general in terms of just the pressure they feel. Because if they if they do not even bad on a test, like if they get like a B and they were expected to like do amazing, they like it's it's this insane pressure that a lot of people feel. And so this film did it started a lot of conversations about that and it changed a lot of the school system. So and that's good because that's I mean, just seeing a little piece of that of that culture in this movie. I mean, that's very dangerous and very scary.  I know when I barely passed. I was like, yes, I've got to do this. But so I just can't imagine on that side. But then also just because as there is different cultural backgrounds, just the idea of like you have to do something like after high school, we were told we had to go to college and we try to do that for a little bit me longer than you and it was a waste of my time, a waste of time and money.  Well, he was saying my passion is engineering. So that's why I'm here. That's why I do this. You know, follow a year, get all your passion.  And I like speaking of Amir, what did you think about his his role and his performance? This is your first experience. So I first I first thought I was like, Oh, is this he special? So this is a real this is I thought this was the forest gum. That's why when I read that, he's going to be perfect. I read he casted him as Boris Gump in this movie just because of his wide eyes and just he looks like look like an alien in a new country kind of thing. And but as it went on, like I really like acting and I really liked how he played both where he could be that serious and have those, you know, tear moments and then also be this, you know, the kind of like he's he's a he's a it was a slacker almost, but a really smart slacker because he he wanted to be there and it wasn't like he had to be there.  I want to be here. I know I'm going to do good and it's not for me anyways kind of thing. And that twist on those twists was crazy. I wasn't expecting that. I was like, what what are you talking about the end made up the entire time? Yeah, talk about the end. Is this a psychological thriller all of a sudden? What do you think about the end and the twist? I like the end. I did like the end. I mean, kind of as much as a romantic I am, I'm kind of over like the easy endings just because I've seen them all the time. So I was kind of expecting.  But at the same time, it was cute. I mean, I got a little teary eyed when and again, I watched here.   This guy watched in Glorious Bastards. And if you haven't seen that movie, there's this huge shootout where like everyone gets gunned down when the movie theaters and this guy's next to me cracking up. Oh, it was it's such a hilarious scene. It was a comedy.  It was so good. And hit the space was that's only. Yeah, that was that was great. Sorry. We're not talking about that movie, though.   So I like I liked it. I like that he was this he was a scientist the whole time. But it was like it was a perfect little though. Yeah, it was. India has as a term for a lot of their films that are called Masala films, which means it has just delicious. Yeah, a bunch of different genres in it. So you'll go from big Bollywood, fun, rom com to a very serious to sad to in all in the same film. And so they call them Masala films just because they this one kind of fit into that. But there are some and I could see that there are some real Masala. This is not one of the ones that kind of defines it. No, I feel like this stayed with that. I think there's big moments that kind of took you away from it. They go, oh, like the the hanging scene, the his friend jumping off the building, the whole having a baby thing. That whole thing was like it took me out. But I think most of it kind of stayed that kind of quirky friendship comedy. But I like that they have that term because that's what I feel about Forrest Gump. That's to bring it back to Forrest Gump. That's like million different movies in one. It's going to be interesting to see how they do that, because it's such an American story that they're going to have to like do so many different things to make it Indian. To go with their history and their culture. I'm curious to see if they're going straight from the movie or the book. Yeah, and see in the books, pretty different. Amir Khan is known for he's called Mr. I think he's called Mr. Perfectionist or something like that. And he also he started in the early 90s. Well, in like his stardom really started in the early 90s. Yeah, but he's and he started in some, you know, quirky leading man roles. But he's since he's got to do what he wants in his career, he's started to wanting to do films with more messaging to them.  And I like this guy. Yeah, he's he's really fine. Unfortunately, we never got to talk to him because he really doesn't do interviews very, very often at all. Because this is one of those we've seen more films of his, I think, than anyone's. Give me more because, yeah. I like I really liked. And what do you think of Karina? Is it the girl, the girl, the love interest? Yeah, I think you saw you saw in her Omkara, actually. She was in Omkara. That's the other Vashal Bardwash Shakespeare one about Othello. Did you ever watch that one? Oh, I never saw. Oh, gotcha. Never mind that. But yeah, I thought she I liked her. I did. I thought she was she was a like nothing stood out. Sorry if I offend people who are fans of the fans of hers. But I thought I thought she was good. But it was just I felt like anyone could play that part. She is a massive star. And that's probably been great stuff. Just here I was like, OK, she's good. She's good love interest. She is a massive, massive star. In terms of like just she's been around along, she actually is in a film called K3G, which you're not ready for yet. Maybe maybe maybe a little while down the road, you will. That was actually going to be by because I was I think I was watching your first one and you said you guys watched it after. Yeah, no, K3G. She plays an iconic character in that one, but not for. Not for like, like it was like an amazing performance. It was like it was one of those just over the top. Just it was an iconic role. OK, her character's name is Pooh Pooh. So, yeah, but yes, she she was and I think she's actually in that. The forcegump one with them, actually, OK, I mean, OK, I mean, yeah, she was she was in bad at all. She did well with what she was doing, but it was just what do you think of the what is a machine scene that's a very iconic scene from this this film? I thought it was really powerful. Yeah, I mean, it was a really good just the message and the way it was delivered. I thought that was again kind of took you out of this fun movie and just really just kind of put things in perspective. And so I thought that was so that's a famous like it's like one of the most famous scenes from the film. What do you think about the professor? I liked him. I really did. Once I got to a part where I realized how over the top this movie was supposed to be and was OK with that, he I liked. I liked his list, but I liked his he was very 90s. Yeah, principal. He was a principal. He was or 80s. He was like fairspieler's day off or a breakfast club.  And so I like I liked him and I like because he was a character. He's definitely he wasn't just playing. You know, I have to be this version of a principal or a dean or whatever. He was his own little fun character. It'd be interesting if I was able to actually watch this where we reviewed it again and see what I thought about it now. Because I know being almost remembering your review 200 films and now in terms of Indian cinema, I think I'd be able to appreciate it more than that. That was my first first ever Indian film. And so his character was definitely striking to me. You definitely need to watch it because I can't imagine. Like, I don't know how I would be if that was my first Indian film. Because I would be OK, this is kind of what I expected.  OK, I suppose to like I suppose we want to keep watching. Like it's like as opposed to a lunchbox and header. Lunchbox and header. Those those were like these are like legit. I mean that that this is not this is a legit movie, too. But these were just movies that were like storytelling. And it was it was about characters and kind of what we fall in love here in America. And so going from that and then to the Bollywood. It just like took me out a little bit. But I love I love musicals always have. And so do you like all the songs? I love the songs I did. I loved all as well. And then the the song with him and with him and her. Zubi, Zubi. I love that. Zubi, Zubi, Zubi, Zubi, Zubi, Zubi, Zubi, Zubi, Zubi, Zubi, Zubi. I stuck my head there sometimes. Like I need to find this on. I too. Oh, they're on there. And then get them and in my workout playlist for Amir Khan. Obviously, there's there's Peket and all that. In terms, he has a bunch. And I don't think we've seen one that we didn't like yet. And we've seen almost 13 of his films. I know one where it looks like a very over the top action movie. And I was like, did you guys see that? No, he's like a gymnast robbing a bank or something. No, I think that's doom three. Yeah, yeah. No, we have not seen to whom three. I'll let you know. Don't watch it. But the ones we've seen, dongle is probably one of his better performances. It's really good. It's a really good film that's and it's a more modern. It's a really good sports film. Dildar Madoo is a good film. He's not really in that. He's a voice in that. Talaash is a good one. That's a police kind of thriller with a little twist in there, which is a good watch. Let's see here. Do, do, do, do, do, do, do, do, do. Oh, Gahan, Gahan Neji. We haven't seen it, but it's the remake of Memento. Oh, yeah. I knew you'd be interested in that one. I haven't seen that one yet. A lot of people say it's really good. You've seen Memento, right? I've never seen Memento. I know about Memento. Right. Oh, another good one. It's it's in the same ilk as three at its NPK is like stars on earth. It's it's he plays a teacher and it's about a kid with autism. It's really good director may might be. Actually, I don't know. No, no, wait. Amir Khan directed. Amir Khan directed like stars on earth. OK, so that's that one's a really good one. Like if you're looking for the same kind of feel as as this in P.K. I would definitely check that one. And then. Oh, Lagan. Lagan, it's a movie about cricket. One, it would help you learn a little bit about cricket. And it was the official entry to the Oscars in 2001 from India. One of the only one of only three Indian films to get nominated for an Oscar, none have ever won. But it's about three and a half hours. Yeah, but it's real good. It's a real good film. That one is a definite, definite recommend even. OK, it's it's one of those. There's a couple films that we've seen that they're three and a half hours like big Bollywood films. But they have so many songs in them. And they kind of they're they're well done in terms of how they're made. And so it doesn't you don't feel as much. Yeah, I mean, if you get hooked in, you forget that. And like I said, with the with three idiots, it took me a while to get hooked in. So it took me a while to kind of finish it. But once I got it. Yeah, but he's definitely one of the actors that we we like more. No, I like him a lot. Let us let Zach know down below what film. Amir Khan film. And if it's not Amir Khan, what film of his he should watch next. Maybe we'll do a poll and we'll have everybody choose what's actually watched next. They might have you watch something terrible. I'll do it. I love to learn a lot of my movies. It's true. And I love them. And then eventually I'm like, OK, that was terrible. Well, let me know down below.


This declaration is the vow of the international community to fight against inhumane treatment and injustice, and to work for the protection of every people's rights. It is a vow to assert the inherent dignity and equal and inalienable rights of all members of the human family, yet today the widespread nature of human rights violations makes a mockery of their commitment to the UDHR. To many, too many states seem to be abandoning their core commitments. The alarming but steady increase of hate and xenophobic rhetoric around the world continues to reinforce discrimination against vulnerable groups. Seventy years after the UDHR, the intensification of these discourses is extremely worrying, with the widespread enthusiasm in different parts of the world for populist movements embracing racist and xenophobic hatred. There is a strong political incentive for many populist leaders, and increasingly for mainstream political parties, to divert attention from the real issues, such as economic and social policies and structures that have led to recession, inequalities and higher levels of precarity worldwide. The world cannot afford to ignore any dimension of the problem of racism, xenophobia and related intolerance, and especially not the forces that do the effective work of structurally subordinating groups on the singular or intersecting basis of their race, ethnicity, national origin, religion, gender, sexual orientation or citizenship status. The time for action is now. Stand up for human rights, stand up for all equal rights. If you wish to get in touch with regards to racial discriminations, xenophobia or related intolerance, please contact me at racism at OHCHR.org.


The introduction of capital asset pricing model in the field of financial economics has been considered as a Significant contribution and the model has been found as an effective and efficient tool in pricing the risky assets but studies on its usefulness Have found certain deficiencies in it and And one such deficiency is its inability to develop a relationship between risk and return There are certain other deficiencies that are available in the empirical literature related to the CAPM It is said that CAPM tests indicate unstable betas for the Individual securities, but stable beta for the portfolios There is mixed sport for positive linear relationship between rate of return and the systematic risk of portfolios of stocks Recent evidence indicate they need to consider more or different risk variables or The proxies thereof There is a limitation of the model in the sense that the model is unable to Select a proxy for market portfolio as a benchmark In an efficient market return differential means the markets are not particularly efficient for extended period of times or The market prices are efficient, but there is something wrong with the way the single model Which is like CAPM may or is the risk The return differential occurs due to knowledge of certain firm or security characteristics market size or The value etc So in the presence of deficiencies with the CAPM what is the alternative? We have an alternative in the name of arbitrage pricing three are the APT Arbitrage pricing theory is an alternative asset pricing model Which is reasonably intuitive it requires Limited assumptions and it allows for multiple dimensions of investment risk factors The assumptions of APT says that the capital markets are perfectly competitive Investors prefer more wealth to less wealth with Certainity and the third is that the stochastic process to generate it asset returns can be expected expressed as a linear relationship between the as a linear relationship function of a set of key factors Unlike CAPM APT does not assume certain other things like a market portfolio that contains all risky Asserts and it is a main variance portfolio The APT also does not assume normally distributed returns It does not assume quadratic utility function So obviously a simple model with the ability to explain different differential security prices will be considered superior theory to the CAPM theory On the screen you can see the APT model in which we have certain factors like we have are We have the betas or the lambdas But these variables Say by are we mean the return on asset I during a specific time period By expected return we mean the expected return for asset I by beta We means the reaction in asset I return to the investments in a common factor by Delta we mean a common factor which has a zero mean and that influences the returns on all assets and that is the factor that is the essence of the APT theory and finally we have the E or the a return which is a unique effect on asset eyes return that by assumption is completely diversifiable in large portfolios and has a mean of zero and Whereby n means a number of assets Delta are the multiple factors or as these factors are Unidentified these are expected to have an impact on all assets these factors may include inflation GDP growth and many others Betas determine how each asset reacts to to this common factors This mean that beta relates the relationship with the factors and the return similar to the CAPM the unique factors are the errors random errors are independent and diversifiable in the larger portfolios APT assumes that in equilibrium the return on a zero investment Zero systematic risk portfolio is zero where the when the unique effects are diversified away This also implies that expected return on any asset I can be expressed in an other equation like E is equal to lambda naught plus lambda B plus lambda to B to plus lambda K and The BK so what these lambdas and betas say Lambda naught is the expected return on the asset with zero systematic risk This means that the lambda naught is equal to E naught or there is no return Lambda J is the risk premium related to the each common factor so this lambda basically is the risk premium of the factor that we are considering as a Factor that is affecting our expected return, which is on the left side of the equation Betas is the pricing Relationship between the risk premium and the asset I this means that this says that how responsive an asset I is to the common factor K There are certain similarities and dissimilarities between APT and the CAPM If we see the form of equation both have linear format If we see the number of risk factor in CAPM, there is only one risk factor. That is the beta But in case of APT, there are K number of risk factors means there are Greater than one risk factors so far as the factor risk premium is there in case of CAPM we have excess market return, but in case of APT we have the lambdas For a factors risk sensitivity in we have betas in the case of CAPM and we also have betas in the case of APT We have zero beta return in CAPM in the form of risk free rate and in the form of Lambda naught we have for the APT


What's up everybody, Jason here for jaspyscasebreak.com. We just sold out 2023 Top Scrum Jumbo eight box case break, picketings number 19. And again, guys, all cards shipped. And let's get to breaking this, guys. So, Alfred got last bought Mojo Red Sox. There you go. Once that one goes, then we'll get a knife. Kippin' address is wrong. Definitely has Duncan said email us. We have a support button on the website or email support at jaspys.com but the support button's a little easier. You just, like I said, hit that button and just say, hey, I just noticed my shipping address is wrong. Here's the right address and then we can manually change that for you. But in your account for future, obviously purchases, you can obviously change that now that you notice that you don't have to worry about that in the future. We're up to the next four. I mean, I can't, I don't have the password. I mean, I guess you can do it in the background if you wanna like pull it up over here. Maybe send that to yourself. Oh, even better. I don't think so. Maybe have plenty. So I'm pretty sure we can upload more. Yeah, that's great. I mean, we've all loved Top's Chrome ripping it. So they said I could open this without spring up the screen, right? Yeah. Yeah, I'll post another one up after this. Like I said, Top's Chrome crowd has always been a little different from like NT. Not to say that there aren't people that bind to both, but Top's Chrome obviously a lot different price point too as well, so I don't think it hurts like other breaks on the website. So, you know, I definitely wanna focus on doing some other stuff that's close, but obviously we can always do a Top's Chrome every day. You know, case the NT a day, keeps the doctor away, same thing with Top's Chrome. Take your Top's Chrome vitamins daily. Good for you. Yeah, they're good for you, right? You just have to go to like the shipping and orders and then look for that day that it's cold and then it should be right there and then just kind of like control after the break that you're looking for. No problem, yeah. I mean, obviously there's still plenty of time. It's not like this is gonna get sorted out right after the break and get shipped out.  Of course, up from the same days or previous days and then ship it out. So we try to tell people it takes usually three business days to about five if we're like super backed up, which obviously with all this Top's Chrome and... Oh, well, I mean, if it wasn't that far along ago, I think it'll be fine. But yeah, good thing you sent that now. I'm not sure. We do have a shipping tab on the website or on our little Google Docs. So you can see if it actually has been sorted or shipped out yet, feels just like a couple of days ago, I think it'll be fine. But yeah, I always just double check that. Cause of course, I mean, sometimes it's out of our control right if the address is wrong or stuff like that. So as long as you guys can catch it beforehand, you can always, with this camera job, I think we have to like, it's like the old one, right? Where we have to kind of like re-focus it or that. Yeah, I think the focus is kind of set, but you can change it to whatever is available for your hands. Gotcha. Do you want to place your hands? Oh yeah, I had it like at 50 or 60. Yeah, so usually like right there, it should be fine. Yeah, cause it's set to 30. Hold on guys, let me pretend I'm gonna hold this card here. That looks good. Nice, yeah. Well, everybody's customer service is a little different when it comes to like, yeah, the bigger companies like that, but I feel like a lot of people have appreciated the tops one. Staphonic and not to put down any other ones, but obviously like, I feel like with Pinini, obviously they've, they're the ones that have like the multiple sports right now and stuff like that, licensing. So obviously it seems like they might be getting a lot more volume of stuff sold and ripped.  Hold on, I think that was the wrong one. Whoa, whoa, what's going on here? Hey Joe, can't remember really quick. I wasn't paying attention to which one I was moving right now. This is right, but what did I do to make it like super, super light like that? Oh, go to camera control and go to exposure. Is that the one I probably moved? Oh, it went back to normal, so I didn't go one way or the other. Okay. Probably minus six and then you can change brightness on the first half. So I don't know why it changed, it was just fine right now. I put it up just a little bit. Yeah, I just don't know which one I moved cause it just all of a sudden got like super, super white. I thought I was moving the focus but I might have been moving the exposure. Yeah. And then you can go to the first half again and shardness is all the way to the right, right? Okay, yeah. Yeah, okay, well, it is what it is guys, I guess. I think that still looks good. You just want to make your cards look good. Yeah, I know. I was just like, I thought I was moving the focus and I was like, I think I moved the other one. All right, here we go guys, let's keep it going. And what do we got here? Kristin Yelich? Nice, orange out of 25. Sure, awesome. Nice, yeah. For sure. I feel like everyone has a different experience too. Read somewhere though that tops obviously with fanatics just trying to make it where I think by like 2024, get reading, getting rid of redemptions. You know, that's something I think they said like Michael Rubin and a lot of them have trying to focus on where get everybody's cards on card or even with a sticker, right? Just ready to roll before even the product is released, which would be freaking awesome. Dream. Paraza, does that get it though? Like I've never been one to complain about redemption so much because obviously sometimes it's less busy for some of these athletes but I mean obviously if they're obligated to sign then they kind of have to. But yeah, if they can get it all done beforehand then that'd be amazing. And also too, I think they were trying to say that it brings the value up of older boxes too in the future, right? So let's just say, you know. No more inspired, right? Yeah, exactly. Let's just say, you know, under Franko's redemption and in 2022, right? You open that up a few years later, right? They might not even have that card anymore. They can't even honor it. About 20 years later we go Hall of Famer? Yeah. So for 10 times the price? Yeah, so a lot of them. So now, obviously, yeah, in the future when there's like a future Hall of Famer, you're like, oh man, I'm gonna go by 2025 because we know that dude's live, right? And it makes the box value up, brings us up even more. Young Carlos Danton. Yeah, and like I said, I'm not once you complain so much of redemption, but if you can get rid of them, whoop!  Is that into that card? It should though, isn't it wireless? It could be wireless, I know. Could be wireless. Caleb Killing. Oh, I don't know. What? There's a case you just shot me? Yeah, it's a tech guy right there. The case is just that. Wanna get me a shamancer box? Do you have a pal? I never got that actually. I hate that when you use, sorry, when you redeem points on the rewards website, you have to pay for shipping, like what is that? But you don't pay for shipping though when they couldn't get you that redemption though, right? Well, at that point then, put the hit in the box for me then, so I don't even have to deal with this, right? Alex Kahl. We have to, give me like 20 of those. Tatis to $2.89. What's that? Yeah, that's fine. 13, I haven't used any of my rewards in years. I have like, I think I have like 3400 points in my Panini rewards and I haven't used it in years, but that's wild. And Michael Massey, it's $1.99. C.J. Stratford in the reception, that said it's over for him. Does it be C.J. Williams? Yeah, it's actually only two today, it looks like. Woo, Bo Jackson, ultraviolet sets up green. That's very nice. And out of $99, $49.99, that's pretty sweet. Last hour of redeem points. Ooh, Drew Lock. I totally believe in that guy. At home point, I met that dude at the Rookie Premier back in 2016, I think it was, 2017, whatever year it was, and, oh no, not 20, that's way too early. That was the other Broncos quarterback. I met him at the 2019, I think, right? He was 2019. I'm doing so much better seeing your chat in this stream now, Rex. You just always make my day. Can't wait to come into work and say, when is Rex gonna chat with me? At a 150, Cody Thomas, Cody Bellinger, John Carlo. It's like, what is Rex gonna talk to me about today, and what am I gonna be able to pick on Rex today with? You know, it's just, it's the thrill of the day. Cody Bellinger, look at that. Keep him in Chicago, right, Rex? At a 125, Asturian Ruiz, Marcus Simeon, negative. What's the years, though? I think that's the most important part. Jordan Walker refractor, 2025 a year, right? So that seems more like a five to seven for like under plus. More like in the 15 million range or so. Nelson Velasquez, Max Mayer to 250. Whoa, speaking of, what was it that just only cubs? It's about a little Adley Rushman to 499 refractor. No man, but the cubs are one of the few teams like the Athletics, the Reds, the A's that just have massive like rookies in their checklist where like that five to seven and they tend to kind of get most of the autos.  We still have half the case left. Corbin Carroll refractor, Nick Castellanos, and Will Brennan, major cut to swings. Yeah, there's definitely always a wall to chuck. I feel like I always hit an Aaron Ashby at some point. I feel like Asturian Ruiz pops out a lot too.  Josh Jung, right? I think everyone says it's supposed to be pronounced a Jung. We hit one nice Adley in this first half. There's a ton of other nice cards here, a ton of colors, or A's tend to pop up a lot guys. I personally feel like I've been hitting a lot of Adley Rushmans of lately too. And especially for Aaron Billings, he was a big Baltimore guy. I feel like I've gotten quite a few Adleys already. And then I did hit that Adley, Gunnar Henderson Super Fractor last week. So I feel like a lot of our cases have had a lot of orioles. Don't get me wrong, we've hit a lot of Corbin Carroll's in that too. I did a, we did a four case Jumbo, or sorry, four case hobby break on Fanatics Live on Tuesday, me and Michael. And for one of our customers that also shops here at Big Dog, he got an orange wave out of 25 Corbin Carroll autographs of a variation. And then Michael, when he ripped, I ripped the orange one. They went Michael was ripping the second half of the case. We did two each. He got a Corbin Carroll, like Aqua Teal, Corbin Carroll at the same time, and one of the other cases. So yeah, I feel like we've been getting a lot of the top players, but I want to say I've been hitting a lot more Adley than anything. I just wish that Super Fractor was live, you know? I really wanted to hit that one live. I had five one-on-ones out of NT yesterday, guys. That was super hot with NT. So let's get some more NT rolling, guys. We're just down to the random number block. And they're not as pricey as the ones that were up yesterday for the first couple bigger teams. And I feel like for the teams remaining in each one of them, they're pretty solid value. We did about like three cases yesterday on the Fanatics Live app. And plenty of really, really nice hits, guys. Plenty. The top camera, the capture to my right. For the Big Hit Express. So, we'll be doing that momentarily after this. We'll upload another Big Hit Express filler. And let's, might as well knock off the tops, or the tops from Jumbopack Break, that unlocks and gives away nine spots in the HipRid dual case for the baseball. And again, let's continue to move those RMBs, guys. Eight left and nine left. I mean, if those be sitting there for a few hours today, guys, I wouldn't doubt it if Nick hasn't already thought of it or planned to obviously create some little pack fillers or box breaks to create a mini filler for the RMB if that helps us sell faster. So, I feel like the teams in there are pretty solid. And for the price point, it's not as pricey as the other ones. So, we can definitely get some done, guys. A roundup for the raise. Starling Marte for the Mets. Josh Smith for the Texas Rangers, that's going to Tristan. All right, we got Salvador Bres, a little relic for the Kansas City Royals. Just going to John. JT Real Muto, nice gold wave to 50. And the Spinoza for the podgers. Three more boxes to go. Brady Furman, Joe Musgrove, a little negative. M.J. Melendez to 399. You have Bryce Johnson for the Giants. Jordan Walker, a fracker, and the next box. Michael Tocalea for the Colorado Rockies. Louisa Reyes to 399 for the Marlins. Olin Gorman, another Bryce Johnson. Come on, man, give me something nice. Emma though, very happy. There you go. Rafael Devers for the Red Sox, 52 out of 75. Olin Gorman, oh, and then Bryce Terang for Milwaukee. Our last box. Hello, Joe guys. Good luck, everybody. So yeah, I'll upload another one. If it hasn't been uploaded just yet, I think we do have enough to do a couple. So Josh Smith for the Texas Rangers. Brett Beatty, Mookie for the Cleveland Guardians. Ryan Boone. Alasios, all right, two base colors, two base autos. Feel like the next one should be a nice color. Ooh, nice Freddie Freeman there for the Dodgers. Remember, that's not sudden stone right now. Who's gonna win MVP from that now? Might be this guy right here. This guy's having an incredible season. And the buyback problem, that could be a hundred bucks. I should have one more auto in here somewhere. Oh man, it's gonna be another base. Mark Vientos for the Mets. Powered though, there you go. All right, the last second on the board. All right, it seems like we just got one bigger, bigger name with the Adley and the K-State Ultraviolets. Good colors, not the craziest rookies. But a lot of colors going out, so a lot of teams at least. And then obviously, quick recap. We'll top load all these. A lot of base autos, I feel like in this one. That was one refractor, a couple repeats. Zarellic, Brennan, Walda Chuck, Thomas, Massey. Paraza, I guess those are Parazza in there. It's Walda Paraza. And you had of course, the Stefanik and the Adley and the K-State there. I guess it was like eight colors. But always want more. So, I appreciate it folks. Like I said, we'll post up another one, but let's try to get some other breaks going, especially the MT-RMB that helps sell out Pikachu number three guys. Appreciate it folks. Jaspy's casebreak stuff now.


Most of the time students ask do you support free software and actually I don't expect more useful answers for it sure and sometimes they want to act like they actually cares about these things so they ask do you go into are we going to use it in real life why not another ambiguous answer so but sometimes you will get accepted as an accident and answer so this guy is actually a lot students sometimes student just answer it due to their domain knowledge so they answer their answers no quite how does like company that Microsoft Office makes money if we just all devoted to free software and he tried to figure out the whole situation with his domain knowledge and then so since he never heard of free software before so he was shocked at this concept and sometimes instead students in my class has a great passion over free software or enthusiasm so he tried to convince that the use the interviewer to use free software but in another hand or in my opinion I think that it's quite similar to a guy trying to retrieve a relationship it just more like they are he is asking do you know and do you know how when a Microsoft Office does cost money because so much Taiwanese are using illegal or they they are using education copy so they don't know the Microsoft Office actually do tax money but sometimes they just it just doesn't seem to work and no matter in which both case and work even harder doesn't grant you many more changes so maybe you just think that the two you are you two are talking in the different language it just don't care about free software the spirit after free software so sometimes the truth is cruel they just don't want to they just don't want to use it yes so actually they just get back to the free software and actually this year and there's a college stop taking new Microsoft license instead of it instead they took liberal office as a substitute solution and the governments do have a policy about pushing open document file format and the college came that they are just following the policy and however a college student do post an article in response to the policy so the article is about are you seriously cut off all Microsoft Office license come on I'm not joking using liberal office is instead of Microsoft Office and I think I don't even heard of liberal office so some students are actually interesting about this topic so they asked their may high school teachers for more answers but somehow teachers came up with the so that free software is more difficult than maybe commercial maybe the official official and normal use one so why does this low stereotype comes from I still don't understand why do people try to even there as their grandparents but surprisingly they do somehow point out some key questions and this is a grandparents that never heard of liberal office instead of instead he only was taught like Microsoft Office the normal office we are using and learning a new thing in one side give us more options to choose what we want to but in another hand will become a burden for students if you still test students about their abilities to use free software and also and finally this is the most important issue price it always comes out so frequently so what I'm trying to say is that the public has a totally diverse opinion to the CS field and familiar students after all so in order to in order to make students into a final project I want to know their interest and we want to figure out what is their curious way why is the curiosity focus on so first let the student do mentioned about the security issue so since the source code is opened and easy to assess and it's easier for maybe for hackers to crackers to mess up with the source code and give a virus one and also some to worry about open source software damage current source market just as I mentioned before just like making developer no interest of making new applications so or at least maybe just give a possible improvement solution on maybe user interface open source sometimes scares people away and people often mistake is of an engineer of engineer only software but a much to my image to my surprise just surprisingly all topic mentioned above is not and used by students they are they don't even care about what I mentioned they are more actually curious about enjoy it and like the mobile phone they use in use in the in the daily life so this is actually one day one proposal they are going to in one proposal of the final project and another one is how to use vendor which is very surprised for a six and computer science group of students and so it makes me start to think about is there a gap between users and the developers so open source did benefit so much student to learn computer software computer science and like Google's number of code it do it does offer many choice choices but for students they never never ever heard of such event everywhere there is only a few students maybe less than 10 heard of or even go through Google some of code but for those who never heard of such event open select open source beginners what what do the word open source mean to them at first five CS students are interested about the keyword open source as a result they want to study the code base of liberal office and trying to figure out how it works and finally they quit yes so they are company about the heavy code base and I do know that it will be have some a also participate in Google some of code but they don't know how to start with and they even trace the coming slow and how how does the how does the new newest patch what is the newest patch to do but it's useless if you want to try trace a in the structure of the whole code so what do open source the means to land and maybe even to the public but it just don't get me wrong for those who already knows free software and get used to it is a total not a story it just like two separate world with huge gap between each side there is a small open source come to student community talking in their own language and you can in this side you can see that even economic affairs shows up in the booth in sitcom encourage students to take up take part in open source project still economic so open source is so famous in Taiwan but almost to the almost same group of people every year and the ticket what is the situation of ticking escape get just getting a consume very very fast so so we try to make a language that can communicate in both sides so as a user so maybe in the figure of speech as a user it is almost always a destination of why are you are using the software so maybe it's your destination of the map and maybe free software is like a bus that always can take always assess always of easy assess for the users but maybe maybe just take slower and what is the commercial software it's more like a car it may cost it but it was it was it was with the faster speed and this is the solution we trying to promote with without any concept of maybe open source and like make sure ability because users are not going to take that and so finally ironic experience in a when I was just trying to act teachers about this topic and what this this policy of the policy actually took place on 2016 and the government decided that it should be fully implement on 2016 so I went back to ask my elementary teacher about this policy and I point out that health of the student on my class never heard of free software and the teacher answers that I don't know it just says oh I don't want free software I do I don't know what what free software is and it is very impressed me since that he's actually a president of and the in charge of the teachers and even in the communication between teachers and students and maybe their parents so they hear through a lot of administration paperwork in his daily life so maybe it's natural for officials like her to get used to ODF five ODF policy so he just asked just a help he was astound by the low amount so I double just as a double check I just asked if she's in the same position as me so I asked can you tell me what the definition of software free software he answered me that Microsoft Office and I suddenly figure out I think it came out that I talked about like office software is not equal to free software and I explained the trade of maybe open source and sure and somehow like that and you will hear from free software promotion and he finally answered this was the difference so he just kept he just pushed me into maybe computer science he just called me to ask to interview another computer science he don't want to involve with this one so this is very very frustrated for when I was interview still teachers or students so I am not getting any any positive feedback so I just want to mention about the gap between users and developers and it's hard for users to accept such an idea since like open source and sure and this is my talk I know it's and so quick but I'm a little bit nervous so but thank you for listening yes and maybe any questions okay thank you


We're out here at La Puente skatepark. This park's really new. This part of the park is like probably about a year and a half old. They just added in this bit of transition here and this really odd pump track over here. If you see, it's not really a pump track, it's pretty much two berms and two rollers. Yeah, it's like a circle with two bumps. Yeah, everything's based so far apart, so you have to push. There's no, you can't pump through that, but yeah. Sean, I have a challenge. At the very least, we need to see a front-side grind. Front grind? Front grind. Let me get, let me feel it out. You can get cozy, you can get cozy. I'm not much of a transitional skater. Don't worry, after today, you will be. You can see, it's like, I don't know, you'll see. Like, I skate it like a mini ramp. It's like very static and like unesthetically pleasing, but it is what it is. We're going to capture it in all its glory. Swag. Ooh, that was kind of tasty. Yep, yep, ooh. How about you get a little turning action in there? There you go. Ooh. Scratch him about dancing when we had to stand up on him and it was sick and now I forget how to do it.  That was it. What's that? It jumped at the end. Afraid of the skateboard? I feel that. Dude, that was kind of sick. I think the coolest part about that was when you got out through your board up. This is what we're dealing with here. Just ride up it a couple of times. Just get comfortable on it. Do I have any good thumbnail? Yeah, such as how did I learn to nose one or something like that? But this is a really playful flat bar. It's like a nice height and usually goes pretty well. We didn't bring any wax. Oh, no, we did bring wax. We did. It's in your car though. Yeah, but we'll see if we have to break it out because this thing is usually pretty good. All I'm saying is that the other day, Zach did a Casper stall. I say not on the end.  Yeah, he's like watching him skate.   All right. Oh, come on. That was it, bro. It is what it is. Do it again. Do it again. One more. One more. First tee. First tee, bro. Who cares? Who cares? First tee, dog. Oh, yes. Oh, yeah. Dude, I had an ex who lived in Chino Hills and in Chino Hills, you know what they got out there? What prison? Tarantulas, bro. Oh, really? Yes. Yeah, dude. Because it's hills. I didn't even realize that like we had those in California. Yeah, they're like big bosses. I never seen it. What's the biggest spider you've seen in Australia? Like this. Oh, maybe one. That was the ones. They eat birds, right?  Oh my God. But the baby ones are like this. So the big ones are like this.  No, they're bottom feeders.  You ever see one in your house? Yeah, all the time. Oh my God. Your house and car.  And dude, I was on the interstate.  I was like, go, go, go, go. Dude, it was crazy.  But like, it was so, I was like, that's an everyday thing. Oh my God. You see a snake? Yeah. What? Yeah, be careful when you garden, especially if you have a garden hose curled up because I'll sit in the middle of it. Oh yeah. I got rattled that the other day by rattlesnake on a one wheel, dude. That's what I get. That's what I get for riding a one wheel. First tee, like nothing. Yes sir. That was it. Whoa, it's a lip. No, I'm trying to get it out. He got it. Blasted. I think that counts. I think that counts, bro. No. That could have been like a swag, like little sketch landing. But when you scream, it ruins it. All right.  This one right here is for the Australian Commonwealth. All right. For the Queen. Sorry for the king, for the king, bro. This one's for the king. I'm not sure how it goes. Charles, do the cops are coming to get you for your illegal trick. I don't know. I'm not at this pool spot.  It's probably known, but I don't want to like blow it out. So we're in this backyard pool. It was a kind of funny little hike up here, but we're up here now. It's only like a six foot pool. So it's kind of steep, but you can still kind of get a line going. I hit tile front side, but I put my hand down on the coping. I don't know if that's lame or not. But yeah, this is like the third or fourth pool I've skated out in California. So it's always fun finding new pools to skate. Considering this is like pretty abandoned, the pool isn't in that bad of a shape. Like there's little holes here and there, but it's not like someone's like shot at it, you know, and like what big holes in the pool. So yeah, I'm going to try to get a few lines and then yeah, I'll show you guys the view. I can only hit two walls. Like I tried to hit the third wall and it just doesn't, I lose all my speed, but I'll try to go that wall, that wall, then that wall and turn around. The fingers crossed. That was fun.   I have a habit of cutting myself when I come to pools. That's what they say, you know, glassware around the swimming pool, but people don't follow the rules. I'm so timid, like on a backside carve for some reason. Very, very timid. I slid down the transition just now. One more. I don't want to do that anymore. Are you recording? Yeah. There's usually a pool light. There's usually a light in the deep end, but I think because this pool is so shallow, there was one in the shallow end, but usually there's a light at the end and you go over it. It's like a trick. But there's no light. So yeah, there's a little love seat though, the waterfall. Fun pool. Very fun, playful pool. So I'll do a couple more front side slashes. I'm trying to aim for the eight ball, like when I go front side. Try to hit the tile, even though I'm using my hand. You got it, babe. Life's a trip. You would have thought I would have been sitting here in a backyard pool. With a Southern California hottie. Honestly, look at this view. There's still 20% off over at eveningmob.com on like shirts and hoodies. So yeah, make sure you go and check out eveningmob.com. I got some new stickers made up. So if you buy something, I'll chuck some stickers in. And yeah, sorry, I just drank this ginger beer, so I'm a bit burpy right now. If you enjoyed this video, leave a thumbs up if you're new here.

So guys in today's video, I'm going to be covering a brand new set of headphones. These are the Fiti hi-fi dots Really excited to try this out. I've reviewed a lot of their branded products in the past I've had many of their headphones. I have a Bluetooth speaker from this brand that I use even till this day Super excited to see how this sounds because I've been a huge fan of the active noise cancelling true wireless headphones This comes in roughly around $200. Take a look at the description below I also have a 20% discount code for you guys so you can get this cheaper than anyone else And not only that this also is complemented with its own dedicated app Which I'll showcase in this video to control some of the features that are with these headphones So let's go ahead and start off with the unboxing and let's get straight into it You can see there's a bit of an instruction there about how to Take out and store the headphones from inside Now this is a really nice design. It's got this very glossy You can see shiny look and it's kind of an egg-shaped design It is actually pretty small fits very easily in the palm of your hands Which means it will very easily fit in your pockets and your backpack before I dive in and look inside there Let's see what else is in the box So you have this lime green USB-C charging cable Three pairs of additional earpieces of different sizes from small to large Quick set of instructions to download the app and the user manual Okay, so let's take a look at the charging case in more detail It has this kind of rose gold trim with the logo in the same color there looks quite nice so you press this little button and It pops open like this very futuristic looking I can see you've got their own little logo just on each of the earpieces So to take these out you actually have to push them to the left and to the right You'll see the LED indicators will showcase the charging status and the pairing status as well Let's go ahead and take this out and actually you can see how compact that is You've got the lime green interior inside the earpiece as well so a very cool design and we are going to be testing the Comfortability of this and one of the things that I also get asked when I test headphones like this is is there any noise leak? So we'll be testing some sample music and seeing if it can be picked up by my microphone With louder volumes and to place them back into the charging case. There's a slot there Where the bottom of the earpiece will fit into like so And then you just close the lid and they are charging So here's a quick snapshot of the key features and specifications of these headphones Now it does have a Qualcomm 3071 chipset which supports snapdragon It also comes with apt x which gives you lossless sound quality Which is always important when you do have true wireless headphones like this It comes with three audio modes mild active noise cancellation strong active noise cancellation and transparency mode having those two different types of active noise cancellations I think is very important and this is the first time i've come across headphones that has this feature It also has dual bluetooth connections So you can pair these two two devices at the exact same time So if you want to connect it to your iphone and your ipad then you can very easily do that And they are ipx 7 water resistant Which means you can very easily use this in the gym when you are sweating And when there's a bit of light rain when you're running outdoors, this would work absolutely fine Okay, so let's go ahead and pair this with my phone for the very first time So you will need to take both earpieces out so that they can connect to each other There we go, and you can see at the bottom of the list Hi-fi dots And they are connected Very quick and easy to do that and before we go ahead and start using the headphones to see how they sound Let's take a look at some of the touch controls So plenty of gestures here and they are touch capacitive earpieces So if you double tap either the left and the right you can answer and phone calls Play and pause your music if you hold it down for one second These are the different modes that you can go to so mild or strong noise cancelling and then go to transparency mode If you tap the earpiece five times, this will turn on or off the low latency mode Again with the left piece, you can also single tap to turn the volume down Triple tap to go to the previous track and with the right earpiece Tap it once to turn the volume up and triple tap to go to the next track So a very convenient set of features on the earpieces themselves to allow you to control it without the need Of using your phone to do that. Okay, so let's take a look at connecting it to the VT app So first of all, let's take out the earbuds from the case So you can open the VT app When you go to add device Go to pair will go to your bluetooth settings And then just make sure that you have connected it so you can see hi-fi dots are connected So you can close this go back to the app go to manual settings And it will appear on the list the first time you do it just make sure your earbuds are charged fully So when you press on that You can see they are now connected So when you go into here multiple different options So i'm going to go ahead and play some music from Spotify whilst I show you these options Okay, I've got some music playing in the background. I'll just put one earpiece on for now And I'll show you what happens with the second earpiece But the ambient sound modes, of course, like I mentioned you have transparency mild noise reduction and strong noise reduction I'm always a big fan of strong noise reduction Earplug test is quite convenient if you wanted to check to see if these fit you comfortably Then when you start the test this will play some music and see if there's a little bit of noise leak Depending on the ambient noise in the background And it will give you the results to see if it is actually a comfortable fit Of course, make sure you have both earpieces in If not, it will tell you that you might need to update something So you can see there in amber just underneath each earpiece It says twist or try out other sizes of earbuds So that's quite convenient. Let's go back You then have equalizer when you go in here, you can make your adjustments as you wish When you go to control So from here, you can actually make the adjustments for the tapping to do different things So for a single tap, for example, right now it adjusts the volume If you go in there, you can actually make it to previous piece Volume up Next track And for double tap, you have the option to let it go to Siri voice assistant Which is quite nice to have that feature as well. It's quite convenient Triple tap, you can also change that to the volume if you want to Then there's five tap and then for holding it down one second, you can make adjustments for that So customize it to however you feel fits your needs Finally at the bottom, we have lighting effect These are the little LED lights that appear on the earpieces So if I turn this on you can switch between breathe Flash and slow So this is the breathe mode. You can see it's slowly pulsating if I go to flash This flash is quite fast If I go to slow, it just flashes very slowly So it's a nice little visual if you want to add that whilst music is playing Then you can actually have that lighting effect on the earpieces So that's quite a nice feature to add into the app Of course, you can see your battery life there as well And it's just convenient to have that in place when you go to settings You have the option to update the firmware So plenty of things you can do from the app when you do connect it And I think that's really nice to have as a complementary to just the earpieces Okay, so now that we've seen the app, let's go ahead and try these on And see how they sound One of the first tests that I always do when I buy a new pair of headphones Is to test how comfortable they are And in fact with this brand all of the headphones that I've had in the past with them Have been one of the most comfortable headphones I've used And when I do my workouts in the gym, I have them on for quite a long time as well They don't fall off They take the sweat from my body quite well and they don't pop out very easily So it does fit quite snug in my earpieces and If you are going to maybe travel long distance, maybe take this on a flight One thing you want to make sure is that it doesn't start hurting after long periods of use So I can see myself very easily wearing these headphones for many hours on end So that's quite important when it comes to comfortability So now let me go ahead and play some tracks from my Spotify One of the questions I always tend to get is Do they have any noise leak? So if you do go on a train and you're commuting to work, for example If you put the volume up a little bit, can the people next to you hear what you're listening to? So we'll test that out and I have my shotgun microphone right next to me to see if you guys can hear some of the noise leak But I'll try out the touch capacitive functions as well to see how easy it is to turn the active noise cancellation on and off And to just change track and change the volume So let's go ahead and play something back now that it's connected Okay, and one of the tests that I always do with the active noise cancellation is to see how much I can hear myself speaking So right now I'm going to just hold this down for one second Okay, so this one is now the strong active noise cancellation And it is a little bit hard to hear myself speak Which is very convenient because when I want to dry out a lot of the background ambient noise Especially when I'm in the gym and they're playing their own music I don't want to listen to it. Just want to concentrate on my music and my workout This is very useful and it actually sounds pretty decent. I'll pause With a double tap. It's actually pretty responsive Increase the volume decrease the volume Yeah, it takes about less than a second for it to register and it actually works fine It doesn't have any swiping gestures. So it is all tapped on the earpieces So let's see how the audio quality sounds It's not too bad. It's actually pretty good I've actually noticed like when you do turn on the strong active noise cancellation It feels like the audio has been boosted a little bit, which means it's a lot clearer Much more easier to hear treble. The bass is slightly more punchier Again, that may be because it's just drowning out more of the background and ambient noises But the quality on the audio I've always been a big fan of and Having that in combination with the long battery life the fast charging on this And also just the comfortability of it. I think, you know, this is kind of like an all-round package And I can see why it's a $200 premium set of headphones So I can't find really any faults with this. I'm super impressed as always Design-wise you can see how nice they look But now what I'm going to do in terms of the noise leak I'm going to just go a little bit closer to my shotgun mic and see if you guys can hear the music coming through This is about 90 volume. So it is pretty loud for me What you guys reckon? I think, you know, for me personally I wouldn't have to worry about going that high in the volume settings So I can keep it around 70% turn on strong a and c And I'm pretty confident nobody will be able to hear that and I can still hear everything that I'm listening to One thing that I may also use this is to connect it to my macbook and then use it to You know, watch my content, Netflix, etc I think it'll be really useful to have this with your streaming because you may want to watch a movie for example And you can just have it on for long periods of time. So it's not necessarily just for music It's pretty much multi-purpose So hopefully, you know, you found that useful the high five dots, you know, quite a nice name very nice design I have to say probably one of the nicest designs. It looks so much better than just my typical air pods pro And yeah, if you're looking on the market for buying a new set of true wireless headphones that pretty much do everything you need Then definitely check out this. I've got the link in the description I've got a 20 discount code for you guys So you can get it cheaper and if you have any questions as always make sure to drop a comment down below And I'll get back to you as soon as I can new videos out every week Make sure to subscribe so you don't miss those ones and I will catch you guys at the next one.
