Question

An airliner carries 100 passengers and has doors with a height of 78in. Heights of men are normally distributed with a mean of 69.0 in and a standard deviation of 2.8 in.

a. If a male passenger is randomly selected, find the probability that he can fit through the doorway without bending.

The probability is

(Round to four decimal places as needed.)

b. If half of the 100 passengers are men, find the probability that the mean height of the 50 men is less than 78in.

The probability is

(Round to four decimal places as needed.)

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.
