Jet Ejection Seats The U.S. Air Force once used ACES-II ejection seats designed for men weighing between 140 lb and 211 lb. Given that women’s weights are normally distributed with a mean of 171.1 lb and a standard deviation of 46.1 lb (based on data from the National Health Survey), what percentage of women have weights that are within those limits? Were many women excluded with those past specifications?

Consider,

*X* be a random variable which represents the weights that follows normal distribution with mean of 171.1 lb and standard deviation of 46.1 lb.

That is,

Step 2

Thus, the required probabilit...
