An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 150lb and 201lb. The new population of pilots has normally distributed weights with a mean of158 lb and a standard deviation of 27.7 lb   If 32 different pilots are randomly​ selected, find the probability that their mean weight is between 150 lb and 201 lb.   The probability is approximately_________   . ​(Round to four decimal places as​ needed.)
