An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 120 lb and 181 lbs. The new population of pilots has normally distributed weights with a mean of 128 lb and a standard deviation of 31.7 lbs. a) If a pilot is randomly selected, find the probability that his weight is between 120 lb and 181 lb The probability is approximately . Round to 4 decimal places as needed
