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 tooexpensive.) Men have hip breadths that are normally distributed with a mean of 14.1in. and a standard deviation of 1.2 in. Find P90. Thatis, 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 asneeded.)
