Hypothesis testing

Hypothesis testing allows us to use an analytical process to determine if a hypothesis is retained or rejected. This process compares a null hypothesis (HO), which states things as we believe they are, to an alternative hypothesis (HA), which proposes a change to what we believe exists.
