COLLE 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 n and a fandard de
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
(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 72 in.
nts
The probability is
(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 he probabilirom part)? Why
O A. The probability from part (a) is more relevant because it shows the proportion of male passengers that will not need to bend.
OB. The probability from part (a) is more relevant because it shows the proportion of flights where the mean height of the male pas ngers wille less
door height
O C. The probability from part (b) is more relevant because it shows the proportion of male passengers that will not need to bend,
OD. The probability from part(b) is more relevant because it shows the proportion of flights where the mean height of the male pass gers will less
