2. 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 and that would be too expensive. Men have hip breadths that are normally distributed with a mean of 14.4 in and a standard deviation of 1 inch.

Find P_99, i.e. find the value that separates the smallest 99% from the largest 1%
