Identify the Z-Score value corresponding to each of the following locations:

Below the mean by a standard deviation of 1

Above the mean by a standard deviation of 1 and 1/2

Below the mean by standard deviation of 3/4

Above the mean by a standard deviation of 2 and 7/8

a.

Z = 1.00

Z = 1.50

Z = .75

Z = 2.875

b.

Z = -1.00

Z = +1.50

Z = -.75

Z = +2.875

c.

Z = +1.00

Z = -1.50

Z = + .75

Z = - 2.875

d. All of them

The following alphas are the most common:

.01

.05

.001

T or F

What is the critical value of Z for a distribution with the alpha set at .01 if the researcher is running a two tailed test?

a. all of these are correct

b. .01

c. 2.33

d. +/- 2.575
