Assume that the population of heights of male college students is approximately normally distributed with mean m of 69 inches and standard deviation s of 3.75 inches. Show all work.

(A) Find the proportion of male college students whose height is greater than 70 inches.
z(70) = (70-69)/3.75 = 0.2667
--
P(x > 70 inches) = P(z > 0.2667) = 0.3949
==============================================
(B) Find the proportion of male college students
whose height is no more than 70 inches
P(x <= 70) = 1-0.3949 = 0.6051
====================================
