An airliner carries 100 passengers and has doors with a height
of 72 in. Heights of men are normally distributed with a mean of
69.0 in and a standard deviation of 2.8 in.
b. If half of the 100 passengers are​ men, find the probability
that the mean height of the 50 men is less than 72 in.
c. When considering the comfort and safety of​ passengers, which
result is more​ relevant: the probability from part​ (a) or the
probability from part​ (b)? Why?
