An engineer is going to redesign an ejection seat for an airplane. The seat was designed for pilot weighing between 129lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 128lb and a standard deviation of 31.2 lb. (B) if 32 different pilot are randomly selected, find the probability of their weight between 120 lb and 161lb. (C) when redesigning the ejection seat, which probability is more relevant.
