When you calculate a z-score you are converting a raw data value to a standardized score on a standardized normal distribution.

It will give you the Average or Mean. To find the area to the right of a z-score first understand that the bell curve has 100 of area beneath it in total. In this picture 100 of the bell curve is shaded. For any z-score the area to its right plus the area to its left must equal 1 or 100.
