An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 130 lb and 181 lb. The new population of pilots has normally distributed weights with a mean of 138 lb and a standard deviation of 32.5 lb. a. If a pilot is randomly selected, find the probability that his weight is between 130lb and 181lb. The probability is approximately (Round to four decimal places as needed.) b. If 34 different pilots are randomly selected, find the probability that their mean weight is between 130lb and 181lb. The probability is approximately (Round to four decimal places as needed.)
