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
42
passengers, and a flight has fuel and baggage that allows for a total passenger load of
6,846
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
6,846 lb42=163
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
181.5
lb and a standard deviation of
37.
The probability is approximately
nothing.
(Round to four decimal places as needed.)
