Question

What kinds of values of test statistic would lead to the rejection of the null hypothesis? In other words, what is the correct form of the rejection region (RR) ?

Answer 1

Answer:

Critical Values and Rejection region

Step-by-step explanation:

Critical Values and Rejection region

• In hypothesis testing, a critical value is a point on the test distribution that is compared to the test statistic to determine whether to reject the null hypothesis.

• If the absolute value of the test statistic is greater than the critical value, we fail to accept the null hypothesis and reject the null hypothesis.
• Critical values depend on the significance level.
• Thus, we may define the rejection region as the region for rejection of null hypothesis and define the region greater than the critical value for a right tailed test and smaller for a left tailed test.
