Question 381194
Assume that the population of heights of female college students is approximately normally distributed with mean m of 65 inches and standard deviation s of 2.75 inches. Show all work.
(A) Find the proportion of female college students whose height is greater than 67 inches.
---
z(67)=(67-65)/2.75 = 0.723
Prop(x> 67 inc) = P(z> 0.723) = 0.2348
---------------------------------------------
(B) Find the proportion of female college students whose height is no more than 67 inches.
Prop(x<= 67) = P(z <= 0.2348) = 0.7652
