Mean Z Score Under a Standard Normal Curve

For a distribution of a standard deviationof o=20 describe the location of the following z scores in its position relative to the mean.
z= +200 is located ________
z= +0.50 is located ________
z= -1.00 is located________
z= -0.25 is located_________

First, you know that the standard normal symmetric about a mean which is 0, right? So the positive z value is on the right of the …

This solution gives detailed steps on how to arrive at the mean z score under a standard normal curve.
