WebThe Null and Alternative Hypothesis. Hypothesis testing is based on making two different claims about a population parameter. The null hypothesis (\(H_{0} \)) and the alternative hypothesis (\(H_{1}\)) are the claims.. The two claims needs to be mutually exclusive, meaning only one of them can be true..
