Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The aircraft can carry 39 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6,396 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be
overloaded if the mean weight of the passengers is greater than
6,396 lb
39
= 164 lb. What is the probability that the aircraft is overloaded? Should the pilot take any action
to correct for an overloaded aircraft? Assume that weights of men are normally distributed with a mean of 183.2 lb and a standard deviation of 39.9.
