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 6,240 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 6,240 lb = 160 lb. What is the probability that the aircraft is overloaded? Should the pilot 39 take any action to correct for an overloaded aircraft? Assume that weights of men are normally distributed with a mean of 177.5 lb and a standard deviation of 36.8
