Q4) An instructor hypothesizes that the standard deviation of the final exam grades in her statistics class is larger for the male students than it is for the female students. The data from the final exam for the last semester are shown. Males n=16 S = 4.2 Females n=18 Sy=2.3 i) Is there enough evidence to support her claim, using a = 0.01? ii) Construct 95% confidence interval for population variances ratio
