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 14.1 in. and a standard deviation of 0.8 in. find upper p 90. that is, find the hip breadth for men that separates the smallest 90% from the largest 10%.
