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%.

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

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..
