Question
An airliner carries
100
passengers and has doors with a height of
74
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
nothing.
​(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
74
in.
 
The probability is
nothing.
​(Round to four decimal places as​ needed.)
 
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?
 
 
A.
The probability from part​ (a) is more relevant because it shows the proportion of male passengers that will not need to bend.
 
B.
The probability from part​ (b) is more relevant because it shows the proportion of male passengers that will not need to bend.
 
C.
The probability from part​ (b) is more relevant because it shows the proportion of flights where the mean height of the male passengers will be less than the door height.
 
D.
The probability from part​ (a) is more relevant because it shows the proportion of flights where the mean height of the male passengers will be less than the door height.
d. When considering the comfort and safety of​ passengers, why are women ignored in this​ case?
