Question 1147830: 6.4 12/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 43 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6 comma 923 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 6,923/43 equals 161
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 182.3 lb and a standard deviation of 38.8.

What is the probability that the sample mean with n=43 is >161
z<(161-182.3)/38.8/sqrt(43)
z<-21.3*sqrt(43)/38.8
z<-3.60. this is for probability aircraft is NOT overloaded.
0.9998 is probability it is overloaded.
