attached is a statistics question

Engineers want to design seats in commercial aircraft so that they are wide enough to fit 90% 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 Pop. That is, find the hip breadth for men that separates the smallest 90% from the largest 10% The hip breadth for men that separates the smallest 90% from the largest 10% is Poo = in. (Round to one decimal place as needed.) 4
