An elevator has a placard stating that the maximum capacity is 4300 lb-28 passengers. So, 28 adult male passengerscan have a mean weight of up to 4300/28 = 154 pounds. Assume that weights of males are normally distributed with amean of 177 lb and a standard deviation of 36 lb.a. Find the probability that 1 randomly selected adult male has a weight greater than 154 lb.b. Find the ability that a sample of 28 randomly selected adult males has a mean weight greater than 154 lb.Question Viewerc. Whatabout the safety of this elevator?youa.

An engineer is going to redesign an ejection seat for the airplane. The seat was designed for pilots weighing between 150 and 191 pounds. The new population of pilots has normally distributed weights with a mean of 158 pounds and a standard deviation or 31.1 pounds. a. If a pilot is randomly selected, find the probability that his weight is between 150 lb and 191 lb. b. If 38 pilots are randomly selected, find the probability that their mean weight is between 150 lb and 191 lb. what is the approximate probability? c. When redesigning the ejection seat, which probability is more relevant? part b because the seat performance for a single pilot is more important part b because the seat performance for a sample of pilots is more important Part a because the seat performance for a single pilot is more important part a because the seat performance for a sample of pilots is more important. please show solving steps and if possible tell me how to also get these answers through excel…

A ski lift states a maximum capacity is 12 people or 2004lb. A worst-case scenario would be 12 adult male passengers since they tend to be heavier verse women and children.
