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 14.9 in. and a standard deviation of 0.9 in. Find Upper P 90. That is, find the hip breadth for men that separates the smallest 90% from the largest 10%.

d =
Step-by-step explanation:
1) To solve for d, isolate it in the equation. So, to get rid of the with the d, add
