Engineers want to design seats in commercial aircraft so that they are wide enough to fit โ95% of all males.โ (Accommodating 100% of males would require very wide seats that would be much tooโ expensive.) Men have hip breadths that are normally distributed with a mean of 14.4 in. and a standard deviation of 1.2 in. Find P95. Thatโ is, find the hip breadth for men that separates the smallest โ95% from the largest 5โ%.
