When wоmen were finаlly аllоwed tо become pilots of fighter jets, engineers needed to redesign the ejection seаts because they had been originally designed for men only. The CES-II ejection seats were designed for men weighing between 140 lb. and 211 lb. Weights of women are normally distributed with a mean of 171 lb. and a standard deviation of 46 lb. If 25 women are randomly selected, find the probability that their mean weight is between 140 lb. and 211 lb. Draw the curve and shade the corresponding area.
