So, it means in this case will become how much 441 power 10 rise to power 10,here it is 100. So, it is again 10 by power 10 then it will become how much 361*10 power 10,this will become how much that is 225*10 power 10.It is now the says square of the lakhs also and then it is 1089 10 power 10 and then we have 1*10power 10 and then we take as the 961. This is the 961*10 rise to power 10, if you sum it up x-xbar square this works out as how much 3178*10 power 10 right. This is the total square you can call it as and for calculating the say s square but you have to do is that is sigma x-x bar whole square x-x bar square by n. So, it means here if you take the n here so, what is this sigma this will be something like this 3178*10 rise to power 10, 3178 10 rise to power 10 n divided by 7. So, this will work out as how much that is 454 10 rise to power 10 right, this will be 454 10 rise to power 10 this is the value of S square.
