The analyst assigned to the project randomly sampled 25 male executives and 25 female executives. Of particular interest to the HR director is whether males have greater variability in miles flown than females. The statistics available below were computed from the samples. Based on these data, what should the HR director conclude if an alpha level equal to 0.05 is used? Click the icon to view the statistics about the number of miles flown. Let sample 1 be males and sample 2 be females. What are the null and alternative hypotheses? O A. Ho of = 03 O B. Ho: o o? O D. Ho: of soz Ha o? > o? O C. Ho: o? z03 Determine the test statistic. E = E (Round to two decimal places as needed.) Determine the critical value. The critical F-value is (Round to two decimal places as needed.) the null hypothesis. There is evidence to conclude that males have greater variability in miles flown than females.
