A survey found that women's heights are normally distributed with mean 63.3 in. and standard deviation 2.2 in. The survey also found that men's heights are normally distributed with mean 69.1 in. and standard deviation 3.7 in. Consider an executive jet that seats six with a doorway height of 55.6 in.

Complete parts (a) through (c) below.

a.) What percentage of adult men can fit through the door without bending?

c.) What doorway height would allow 40% of men to fit without bending?

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.
