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 150lb and 191lb. Weights of women are now normally distributed with a mean of 169 lb and a standard deviation of 38 lb. Complete parts (a) through (c) below.

Question
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 150lb and 191lb. Weights of women are now normally distributed with a mean of 169 lb
and a standard deviation of 38 lb.
Complete parts (a) through (c) below.
and a standard deviation of 38 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
191
lb.The probability is approximately

(Round to four decimal places as needed.)Part 2
b. If
35
different women are randomly selected, find the probability that their mean weight is between
150
lb and
191
lb.The probability is approximately
enter your response here.
(Round to four decimal places as needed.)Part 3
c. When redesigning the ejection seat, which probability is more relevant?
The part (b) probability is more relevant because the seat performance for a sample of pilots is more important.
The part (b) probability is more relevant because the seat performance for a single pilot is more important.
The part (a) probability is more relevant because the seat performance for a sample of pilots is more important.
The part (a) probability is more relevant because the seat performance for a single pilot is more important.
