Suppose that passengers on flights average 185 pounds and that those weights have a standard deviation of 50 pounds. Consider a simple random sample of 162 passengers (the capacity of a Boeing 737 with a two-class configuration). a. Find the probability that the average weight of the 162 passengers is under 190. b. Consider part a but for a simple random sample of 5 such passengers. Under what condition could you use the same method to compute that probability? Dio you think this condition is satisfied? Explain.
