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 14.5 in. and a standard deviation of 1.1 in. find upper p 99. that is, find the hip breadth for men that separates the smallest 99% from the largest 1%.
the hip breadth for men that separates the smallest 99% from the largest 1% is upper p(99)=
