Thus, one rejects the null hypothesis if the observed test statistic is more extreme in the direction of the alternative hypothesis than one can tolerate.

In this method, we test some hypothesis by determining the likelihood that a sample statistic could have been selected, if the hypothesis regarding the population parameter were true.

How is the critical value of a hypothesis determined?

Critical Value (CV) – separates the critical region from the non-critical region, i.e., when we should reject H 0 from when we should not reject H 0. The location of the critical value depends on the inequality sign of the alternative hypothesis. Depending on the distribution of the test value, you
