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 191 lb. Weights of women are now normally distributed with a mean of 175 lb and a standard deviation of 46 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.) b. If 28 different women are randomly selected, find the probability that their mean weight is between 150 lb and 191 lb. The probability is approximately. (Round to four decimal places as needed.)
