Which of the following is true about the critical value and the test statistic? A critical value is calculated based on the observed sample data and is compared to the test statistic to determine whether the sample provides sufficient evidence to reject the null hypothesis. If the critical value is in the rejection region of the graph, the null hypothesis must be rejected. The test statistic is calculated based on the observed sample data and is compared to the critical value to determine whether the sample provides sufficient evidence to reject the null hypothesis. None of the above.

Solution

It is OPTION C, which explains itself:

C: The test statistic is calculated based on the observed sample data and is compared to the critical value to determine whether the sample provides sufficient evidence to reject the null hypothesis. [ANSWER]
