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 tooexpensive.) men have hip breadths that are normally distributed with a mean of 14.5 in. and a standard deviation of 1.2 in. find upper p90. 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 p90__in.

(round to one decimal place as needed.)
