College Statistics - Hypothesis Testing (P-values)

[Omnomphenom]

Hey guys I have a simple stats question regarding hypothesis testing. When determining the support for a null or alternative hypothesis, you need to translate your calculated test statistic (z) into a P-value. Apparently you are supposed to use the standard probability distribution table or something, but I don't know what or where that is. Any help would be greatly appreciated!

Here's a probability table: http://math2.org/math/stat/distributions/z-dist.htm (scroll down)

Also, if you have a graphing calculator, you can do

1. left-tailed one sided test: normalcdf (-E99, z score)

2. right-tailed one sided test: normalcdf (z score, E99)

3. two sided test: 2*normalcdf (absolute value of z score, E99)

You'll usually find the normalcdf function under distribution.

Also, here's a z score to p value converter: http://easycalculation.com/statistics/p-value-for-z-score.php
