K 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 140 lb and 211 lb Weights of women are now normally distributed with a mean of 172 lb and a standard deviation of 45 lb Complete parts a through c below CIXE a If 1 woman is randomly selected find the probability that her weight is between 140 lb and 211 lb The probability is approximately Round to four decimal places as needed b If 33 different women are randomly selected find the probability that their mean weight is between 140 lb and 211 lb The probability is approximately Round to four decimal places as needed c When redesigning the ejection seat which probability is more relevant OA The part b probability is more relevant because the seat performance for a single pilot is more important OB The part a probability is more relevant because the seat performance for a sample of pilots is more important OC The part a probability is more relevant because the seat performance for a single pilot is more important OD The part b probability is more relevant because the seat performance for a sample of pilots is more important
