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
----
x = 2.0537*1+14.4
---
x = 16.45 inches
=====================
First step, expand the left side (multiply together) (apply FOIL/distribution property)
2nd step, solve so that one side is zero, by adding/subtracting like terms
3rd step, solve for x
