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

Answer:
Step-by-step explanation:
Area = 0.5(base)(height)
= 0.5(16.9)(10.4)
= 87.88 sq ft
Firstly, find the radius with the formula diameter (d) : 2
8 : 2 = 4 cm
The Vilume formula is r²hπ = 4²*12*π = 16*12*π = 192π cm³
Your exercise says to use "3" as a value for π
Then V is 192*3 = 576 cm³
