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 14.4 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:

x = 16.45 inches

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

 

----

x = 2.0537*1+14.4

---

x = 16.45 inches
