(a) chicken delight claims that the mean wait time for an order is 5 minutes or less. a sample of 50 orders revealed a mean wait time of 5.3 minutes. the standard deviation is 1 minute. using a level of significance of 0.05, carry out a hypothesis test for chicken delight’s claim using the 6-step procedure. (b) suppose that someone says that the p-value for the scenario in part (a) is 0.17. is that possible? why or why not?

An engineer is going to redesign an ejection seat for an airplane. the seat was designed for pilots weighing between 120 lb and 161 lb. the new population of pilots has normally distributed weights with a mean of 125 lb and a standard deviation of 28.1 lb. a)if a pilot is randomly selected, find the probability that his weight is between 120 lb and 161 lb. the probability is approximately? b. if 36 different pilots are randomly selected, find the probability that their mean weight is between 120 lb and 161 lb. the probability is approximately? c. when redesigning the ejection seat, which probability is more relevant? . part (b) because the seat performance for a single pilot is more important. b. part (b) because the seat performance for a sample of pilots is more important. c. part (a) because the seat performance for a sample of pilots is more important. d. part (a) because the seat performance for a single pilot is more important.
