SE This Question: 2 pts 10 of 10 (1 complete) This Test: 25 pts possible In a certain city, the average 20- to 29-year old man is 69.6 inches tall, with a standard deviation of 3.1 inches, while the average 20- to 29-year old woman is 64.3 inches tall, with a standard deviation of 3.9 inches. Who is relatively taller, a 75-inch man or a 70-inch woman? Find the corresponding z-scores. Who is relatively taller, a 75-inch man or a 70-inch woman? Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places as needed.) O A. The z-score for the woman, is smaller than the Z-score for the man, so she is relatively taller. B. The z-score for the man, is smaller than the z-score for the woman, so he is relatively taller. C. The z-score for the woman, is larger than the Z-score for the man, so she is relatively taller. D. The Z-score for the man, is larger than the z-score for the woman, so he is relatively taller. o The accompanying data represent the muzzle velocity (in meters per second) of rounds fired from a 155-mm gun. 793.8 793.1 |792.4 794.0 791.4 1792.4 791.7 792.3 789.6 794.4 (a) Compute the sample mean and median muzzle velocity.
