An engineer is going to redesign an ejection seat for an airplane. The seat was designed for plots weighing between 150 band 201 ib. The new population of pilots has normally distributed weights with a mean of 158 ib and a standard deviation of 27.9 ib. 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 150 lb and 2016 The probability is approximately (Round to four decimal places as needed.) b. If 34 different pilots are randomly selected, find the probability that their mean weight is between 150 lb and 2011 The probability is approximately (Round to four decimal places as needed.) c. When redesigning the ejection seat which probability is more relevant? A Part (b) because the sent performance for a sample of pilots is more important B. Part(b) because the seat performance for a single pilot is more important, C. Part (a) because the sent performance for a single pilot is more important. D. Part(a) because the seat performance for a sample of pilots is more important
