3E1. Heights of college women have a distribution
that can be approximated by a normal curve with a
mean of μ=65 inches and a standard deviation
equal to o=3 inches. About what proportion
65-<2<67- of college women
P(65 < X < 67)=P(65-H
σ
are between 65 and 67 inches tall?

3E1. Pulse rates X of adult men are
approximately normal with a mean of 70 and a
standard deviation of 8. Which choice correctly
describes how to find the proportion of men that
have a pulse rate greater than 78?
[P(X>78)=P(Z > 78-H)=P(Z > 1)].
(5) Find the area to the left of z = 1 under a
standard normal curve. (y) Find the area between
z=-1 and z= 1 under a standard normal curve.
(e) Find the area to the right of z=1 under a
standard normal curve. (y) Find the area to the
right of z=-1 under a standard normal curve.
