Question
14 ( B and C )
When women were finally allowed to become pilots of fighter jets, engineers needed to redesign the
ejection seats because they had been originally designed for men only. The ejection seats were
designed for men weighing between 150 lb and 221 lb. Weights of women are now normally
distributed with a mean of 172 lb and a standard deviation of 37 lb. Complete parts (a) through (c)
below.
a. If 1 woman is randomly selected, find the probability that her weight is between 150 lb and 221 lb.
The probability is approximately 0.6290. (Round to four decimal places as needed.)
b. If 29 different women are randomly selected, find the probability that their mean weight is between
150 lb and 221 lb.
The probability is approximately (Round to four decimal places as needed.)
