Textbook Problem

For a distribution with a standard deviation of σ = 20, describe the location of each of the following *z*-scores in terms of its position relative to the mean. For example, *z* = +1.00 is a location that is 20 points above the mean.

**a.** *z* = +2.00

**b.** *z*=+0.50

**c.*** z=*–1.00

**d.*** z =*–0.25
