The U.S. Army is concerned with the quality of enlisted personnel who are being selected for Officer Candidate School. They fear that the old army rule of picking leaders by selecting the tallest person in the platoon is having an effect on the selection process. For male soldiers, they know that the average height is 70 inches. A sample of 75 persons who have been selected for OCS is taken. These soldiers have an average height of 73 inches, with a standard deviation of 8 inches. Present a hypothesis, a null hypothesis, evaluate the hypothesis (reject the null hypothesis or not), and explain what you have found.
