Goal: We want to use information from a sample to decide whether or not to reject the claim being made.
Set up:
1. Define two mutually exclusive hypotheses with respect to the claim that is being made.
Note: Traditionally, we assign the claim that we are trying to verify to Ha and let H0 be the counterclaim.
(H0 is often expressed as a statement of “no difference” or “no effect”. (i.e the status quo))
