Engineers want to design seats in commercial aircraft so that they are wide enough to fit 95% 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 14.2 in. and a standard deviation of 0.9 in. find upper p 95. that is, find the hip breadth for men that separates the smallest 95% from the largest 5%.

Ответ:
The answer is 15.68 in
Explanation:
X~N(μ=14.2; σ=0.9)
I want to find "a", so:
Z~N(0; 1)
Φ(-15.78)≅0
Based on the Standard Normal table
if
(a-14.2)/0.9=1.64485, then a=15.68
