Suppose that you gather a sample of 34 sea turtles from location A and measure their lengths, and you sample 45 sea turtles from location B and measure their lengths. The table below summarizes some statistics for these samples; the units of length are centimeters. Location A Location B Arithmetic Mean 43.27 35.48 Median 44.87 38.54 Standard Deviation 3.56 2.41 You will also use this data for the questions following this one. Based only on the data given above, which would you more confidently estimate is the distribution closest to a normal distribution? Note: You should be able to explain why. Location B Location A

Question
Suppose that you gather a sample of 34 sea turtles from location A and measure their lengths, and you sample 45 sea turtles from location B and measure their lengths. The table below summarizes some statistics for these samples; the units of length are centimeters. Location A Location B Arithmetic Mean 43.27 35.48 Median 44.87 38.54 Standard Deviation 3.56 2.41 You will also use this data for the questions following this one. Based only on the data given above, which would you more confidently estimate is the distribution closest to a normal distribution? Note: You should be able to explain why. O Location B O Location A QUESTION 10 Round all answers to 4 decimal places. a) What is the associated right/upper-tail test statistic for a test on homoscedasticity between the sea-turtle lengths of the two populations? b) What is the associated p-value for the test statistic calculated in (a)? c) If you choose an alpha value of 1%, based on you p-value only, do you have evidence to believe that the populations are homoscedastic to one another? (type either "yes" or "no")
