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 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. Hoi o? =03 O B. Hoi of ±o? OC. Hoi of 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 V evidence to conclude that males have greater variability in miles flown than females.
Unitary Method
The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.
Speed, Time, and Distance

Profit and Loss
The amount earned or lost on the sale of one or more items is referred to as the profit or loss on that item.
Units and Measurements
Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
Please make sure to round to 2 decimal places.
