Question: 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.

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 138 lb and a standard deviation of 26.5 lb

a. If a pilot is randomlyselected, find the probability that his weight is between 130 lb and 171 lb.

What is the probability? (Round to four decimal places asneeded.)
