Question
Suppose that an airline uses a seat width of 16.3 in. Assume men have hip breadths that are normally distributed with a mean of 14.5 in. and a standard deviation of 1
in. Complete parts (a) through (c) below.
(a) Find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.3 in.
The probability is -
(Round to four decimal places as needed.)

The probability is
(Round to four decimal places as needed.)
(c) Which result should be considered for any changes in seat design: the result from part (a) or part (b)?
The result from
should be considered because
