Q:

Engineers want to design seats in commercial aircraft so that they are wide enough to fit 99% of all males. Men have hip breadths that are normally distributed with a mean of 14.2 in. And a standard deviation of 0.9 in. Find P99 that is, find the hip breadth for men that separates the smallest 99% from the largest 1%

Answer:Step-by-step explanation:Engineers want to design seats in commercial aircraft so that they are wide enough to fit 98% of all males. Men have hip breadths that are normally distributed with a mean of 14.4 inches and a standard deviation of 1 inch. find P98. I really don't understand, help needed please. ----------------------- Find the z-value with a left tail of 0.98 invNorm(0.98) = 2.0537 ----- Find the corresponding x-value using x = zs+u Β ---- x = 2.0537*1+14.4 --- x = 16.45 inches =====================
