Question

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

passengers, and a flight has fuel and baggage that allows for a total passenger load of

6,080

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

6,080 lb38=160

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

176.9

lb and a standard deviation of

37.

The probability is approximately

nothing.

(Round to four decimal places as needed.)

Should the pilot take any action to correct for an overloaded aircraft?

Yes. Because the probability is high, the pilot should take action by somehow reducing the weight of the aircraft.

No. Because the probability is high, the aircraft is safe to fly with its current load.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
