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 14.7in. and a standard deviation of 1.2in. Find 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=nothing in. (Round to one decimal place as needed.)

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
14.7in. and a standard deviation of 1.2in. Find 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=nothing in.
(Round to one decimal place as needed.)
