An engineer is going to redesign an ejection seat for anairplane. The seat was designed for pilots weighing between 150lband 201lb. The new population of pilots has normally distributedweights with a mean of 158lb and a standard deviation of 34.2lb.
a. If a pilot is randomly​ selected, find the probability thathis weight is between 150lb and 201lb.
b. if the number different pilots are randomly selected, findthe probability that their mean weight is between 150lb and201lb
c. When redesigning the ejection seat, which probability is morerelevent ?
