U.2.1-1 Question Help
Engineers want to design seats in commercial aircraft so that they are wide enough to fit 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 14.1 in and a standard deviation of 1.1 in. Find P99 That is, find the hip breadth for men that separates the smallest 99% from the largest 1%.
