An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 130 lb and 171 lb. The new population pilots has normally distributed weights with a mean of 136 lb and a standard deviation of 26.8 lb. Click here to view page 1 of the standard normal distribution. Click here to view page 2 of the standard normal distribution a. If a pilot is randomly selected, find the probability that his weight is between 130 lb and 171 lb. The probability is approximately 0.4920 (Round to four decimal places as needed.) b. If 40 different pilots are randomly selected, find the probability that their mean weight is between 130 lb and 171 lb. The probability is approximately (Round to four decimal places as needed.)

K An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilots weighing between 130 lb and 171 lb. The new population of pilots has normally distributed weights with a mean of 136 lb and a standard deviation of 26.8 lb. Click here to view page 1 of the standard normal distribution. Click here to view page 2 of the standard normal distribution. a. If a pilot is randomly selected, find the probability that his weight is between 130 lb and 171 lb. The probability is approximately 0.4920. (Round to four decimal places as needed.) b. If 40 different pilots are randomly selected, find the probability that their mean weight is between 130 lb and 171 lb. The probability is approximately (Round to four decimal places as needed.)
