Answer:
Step-by-step explanation:
Given that X, the hip width of men is N(14.2, 0.9)
i.e. we have is N(0,1)
Seat width an airline uses = 16.7 inches.
a) the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.7 in
b) Here sample size = 126
Each person is independent of the other
the probability that these men have a mean hip breadth greater than 16.7
= <0.00001
c) part a is important since even a single person not fitting will cause embarassment and leads to customer dissatisfaction.
