Question

Draw a vertical line through a normal distribution for each of the following z-score locations. Determine whether the body is on the right or left side od the line and find the proportion in the body.
a. z= 2.20
b. z= 1.60
c. z= -1.50
d. z= -0.70

This is a little clearer. The larger portion (body) for positive Z scores is to the left. For negative Z scores, it is to the right.

Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability in the larger portion for each Z score.
