A hypothesis test is a rule that specifies, for a null hypothesis $H_0$ and alternative hypothesis $H_1$:

• For which sample values the decision is made to accept $H_0$
• For which sample values $H_0$ is rejected and $H_1$ is accepted.

Consideration of a suitable test statistic $T$ enables the null hypothesis to be rejected at a given significance level $\alpha$ only if $T$ lies in its critical region for $\alpha$.
