Learn how to formulate null and alternative hypotheses, calculate p-values, and decide when to reject or accept the null hypothesis based on significance levels. See examples of one- and two-tailed predictions and how they affect the decision criteria.

You reject the null hypothesis when your test value falls into the rejection region. If you are able to reject the null hypothesis in Step 2, you can replace it with the alternate hypothesis. The exact method you follow depends mainly on if you have a proportion or a p-value: P Value Instructions. Proportion Instructions.
