(A) Find the proportion of male college students whose height is greater than 70 inches.

(B) Find the proportion of male college students whose height is no more than 70 inches.

Is this correct?

a) z=(70-69)/3.75 = .2667

.5+.1026 = .6026

b) 1-.6026 = .374 or 37.4%

any help is appreciated

- stats (please help) -
**drwls**, Friday, July 22, 2011 at 12:50amYour z is correct, but I get 39.5% for (A) and 60.5% for (B)

Clearly there are less than 50% with heights of 70 inches and above if 69 is the mean.
