plz help this question

O Engineers want to design seats in commercial aircraft so that they are wide enough to t 99% 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 14.8 in. and a standard deviation of 1.1 in. Find P99. That is, nd the hip breadth for men that separates the smallest 99% from the largest 1%. The hip breadth for men that separates the smallest 99% from the largest 1% is P99 = D in. (Round to one decimal place as needed.)
