Question

What are the two decisions that you can make from performing a hypothesis test?how is that decision made?

Answer 1

By performing a hypothesis test, we can make two decisions, either we can reject the null hypothesis or fail to reject the null hypothesis.

If we reject the null hypothesis, we can say that there is sufficient evidence to support our claim (alternative hypothesis). If we fail to reject the null hypothesis, we can say that there not sufficient evidence to support our claim (alternative hypothesis).

Usually we use pvalue approach.

If alpha > pvalue, we reject null hypothesis.

If alpha < pvalue, we accept null hypothesis
