Suppose that an airline uses a seat width of16.3 in. Assume men have hip breadths that are normally distributed with a mean of14.1 in. and a standard deviation of0.9 in. Complete parts(a) through(c) below.

(a) Find the probability that if an individual man is randomlyselected, his hip breadth will be greater than16.3 in.

The probability is

(Round to four decimal places asneeded.)

(b) If a plane is filled with115 randomly selectedmen, find the probability that these men have a mean hip breadth greater than16.3 in.

The probability is

Part 3

(c) Which result should be considered for any changes in seatdesign: the result from part(a) or part(b)?

The result from

part (b)

part (a)

should be considered because

only average individuals should be considered.

the seats are occupied by individuals rather than means.
