a. If a pilot is randomly selected, find the probability that his weight is between 150 lb and 211 lb. The probability is approximately. (Round to four decimal places as needed.) b. If 36 different pilots are randomly selected, find the probability that their mean weight is between 150 lb and 211 lb. The probability is approximately. (Round to four decimal places as needed.) c. When redesigning the ejection seat, which probability is more relevant? O A. Part (a) because the seat performance for a single pilot is more important. O B. Part (b) because the seat performance for a single pilot is more important. OC. Part (b) because the seat performance for a sample of pilots is more important. O D. Part (a) because the seat performance for a sample pilots is more important.
