An airliner carries 250 passengers and has doors with a height of 75 in. Heights of men are normally distributed with a mean of 69.0

in and a standard deviation of 2.8 in. Complete parts (a) through (d).

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

The probability is 0.9838

(Round to four decimal places as needed.)

b. If half of the 250 passengers are men, find the probability that the mean height of the 125 men is less than 75 in.

The probability is nothing.

(Round to four decimal places as needed.)
