how do you approach these kind of questions?  (a) In an
experiment, the following survival times (in minutes) were
recorded, under a certain condition, of the peroneal nerves of
four cats and ten rabbits.  Cats: 25 33 43 45 Rabbits: 15 16 16
17 20 23 28 28 35 35  Use a randomization test to investigate
whether these samples are from the same distribution. You should
define your null and alternative hypotheses, and state clearly
what you can conclude from the results of your test.  (b)
Consider the following data relating to the mandible lengths (in
millimetres) of 10 male golden jackals "Canis aureus" in the
collection at the British Natural History Museum:  Males: 120
107 110 116 114 111 113 117 114 112  Calculate an estimate of
the mean mandible length for male golden jackals, given the
observed data. Calculate the standard error of your estimate for
the mean mandible length (using the bootstrap technique)
