After you select the appropriate test statistic,you ______.

A) provide a statement of the null hypothesis
B) compute the test statistic value
C) set the level of significance
D) determine the critical value needed for rejection of the null hypothesis

Test Statistic

A metric derived from sample information in a hypothesis test, utilized to determine the rejection of the null hypothesis.

Null Hypothesis

A statistical hypothesis that assumes no difference or effect in a particular situation, often set to be tested against an alternative hypothesis.

Level of Significance
