15. Southwest Airlines Seats Southwest Airlines currently has a seat width of 17 in. Men have hip breadths that are normally distributed with a mean of 14.4 in. and a standard deviation of 1.0 in. (based on anthropometric survey data from Gordon, Churchill, et al.). a. Find the probability that if an individual man is randomly selected, his hip breadth will be greater than 17 in. b. Southwest Airlines uses a Boeing 737 for some of its flights, and that aircraft seats 122 pas- sengers. If the plane is full with 122 randomly selected men, find the probability that these men have a mean hip breadth greater than 17 in. c. Which result should be considered for any changes in seat design: the result from part (a) or part (b)?

15. Southwest Airlines Seats Southwest Airlines currently has a seat width of 17 in. Men
have hip breadths that are normally distributed with a mean of 14.4 in. and a standard deviation
of 1.0 in. (based on anthropometric survey data from Gordon, Churchill, et al.).
a. Find the probability that if an individual man is randomly selected, his hip breadth will be
greater than 17 in.
b. Southwest Airlines uses a Boeing 737 for some of its flights, and that aircraft seats 122 pas-
sengers. If the plane is full with 122 randomly selected men, find the probability that these men
have a mean hip breadth greater than 17 in.
c. Which result should be considered for any changes in seat design: the result from part (a) or
part (b)?
