The human resources director of a large company recently asked her staff to conduct a study of the airline miles traveled by executives of the company during the most recent calendar year. The analyst assigned to the project randomly sampled 17 male executives and 17 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? A 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 = o3 O B. Ho: of #o? OC. Ho: o z03 O D. Ho: of so? Determine the test statistic. F= (Round to two decimal places as needed.) Determine the critical value. The critical F-value is (Round to two decimal places as needed.) v the null hypothesis. There is evidence to conclude that males have greater variability in miles flown than females.
