An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 130 lb and 191 lb. The new population of pilots has normally distributed weights with a mean of 136 lb and a standard deviation of 27.9 lb. A.) if a pilot is randomly selected, fidn the probability that his weight is between 136 lb and 191 lb. The probability is approximately ____ (Round to four decimal places as needed) B.) If 33 differnet pilots are randomly selected, find the probability that their mean wiehg is between 130 lb and 191 lb. The probability is approximately _____ (round to four decimal places)
