Engineers want to design seats in commercial aircraft so that they are wide enough to fit 9090% 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 14.814.8 in. and a standard deviation of 1.11.1 in. find upper p 90p90. that is, find the hip breadth for men that separates the smallest 9090% from the largest 1010%. the hip breadth for men that separates the smallest 9090% from the largest 1010% is upper p 90p90equals= nothing in.
