Online calculator: Z-score from P-value - PLANETCALC
https://planetcalc.com/7803However, the calculator below can calculate the z score for an arbitrary p-value. It is not that hard if you can calculate the inverse of CDF (cumulative distribution function) for standard normal distribution. And I can, thanks to excellent jStat library. Now, let me give you a couple of illustrations of how it works for various hypotheses.
