Heights аre generаlly nоrmаlly distributed. Men have a mean оf 69.5 inches and standard deviatiоn 2.4 inches. Women have a mean of 63.8 inches and standard deviation 2.6 inches. The US Air Force has a height requirement for their pilots to be between 64 inches and 77 inches. Make sure you are rounding z-scores properly to two places. Part A: Find the two z-scores for women who meet this height requirement z = [BLANK-1] (smaller value) and z = [BLANK-2] (larger value) Part B: Using the z-scores from part A, find the proportion of women who meet the height requirement. Give this answer as a decimal. [BLANK-3] Part C: Find the two z-scores for men who meet this height requirement z = [BLANK-4] (smaller value) and z = [BLANK-5] (larger value) Part D: Using the z-scores from part C, find the proportion of men who meet the height requirement. Give this answer as a decimal. [BLANK-6] Part E: If the height requirement were changed to exclude only the shortest 1% of women and tallest 1% of men, what are the new heights? The short value would be [BLANK-7] in inches and the tall value would be [BLANK-8] in inches. Please give these two values rounded properly to one decimal place.
