Engineers want to design seats in commercial aircraft so that they are wide enough to fit 9090​% 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 14.614.6   in. and a standard deviation of 1.21.2 in. Find Upper P 90P90. That​ is, find the hip breadth for men that separates the smallest 9090​% from the largest 1010​%.
