**PsyDAG**, Monday, August 18, 2008 at 11:48amCalculate Z scores for both values.

Z = (x-μ)/SD, where x = score, μ = mean, and SD = standard deviation.

In table on back of your statistics book called something like "areas under normal distribution," use Z scores to find areas between scores and mean. Add the two values.

I hope this helps. Thanks for asking.
