Engineers want to design seats in commercial aircraft so that they are wide enough to fit 95% of all
males. (Accommodating 100% of males would require very wide seats that would be much too expensive.) Men have
hip breadths that are normally distributed with a mean of 14.2 in. and a standard deviation
of 1.1 in. Find P95. That is
,
find the hip breadth for men that separates the smallest 95% from the largest 5%.
