2. Women in the U.S. Air Force have hands that are 6.9 inches long on average (from the tip of the middle finger to the heel of the hand). The standard deviation is .34 inches. Assume that hand length is normally distributed. A. What proportion would have hands 7 inches or longer? Be sure to draw a graphic to visualize your answer. B. What proportion would have hands 6 inches or shorter? Be sure to draw a graphic to visualize your answer. C. Of 3000 women in the U.S. Air Force, how many would have hands 7.5 inches (the mean for male Air Force personnel) or longer? Hint: first find the percentage associated with having a hand size of 7.5 inches or higher, and then multiply it by the number of women in the given population. D. What is the minimum hand length needed to be in the top 20% of hand sizes? Hint: you're given a percentage and you need to find the X score that goes with it. Find the column A z-score value associated with 20%, then plug that value into your z-score formula. Use algebra to find X
