Title: PValue changes

Renamed PValue.java to ZTest.java since that's the actual statistical test being performed here. The term p-value really applies to any statistical test, so this rename seems more accurate.

I also added more table lookup values to improve accuracy, and made a change to return p-values (before the method was returning 1 - p-value).
