Explanation / Answer

Question 2

Answer: C

Explanation:

In null hypothesis, we are dealing with the statements with ‘=’, ‘’, or ‘’ signs only. In alternative hypothesis, we are dealing with the statements with ‘<’, ‘>’, or ‘’. Also, statement should represent the claim properly which is described in the research study. Given claim is dealing with the blood pressure of the patients with high blood pressure. These facts are presented in statement C, so this statement can be stated as null hypothesis.

Question 3

Answer: C

Explanation:

If we reject the null hypothesis at = 0.01, this means the p-value should be less than = 0.01, so we should reject the null hypothesis at = 0.05 also.

Answer: A

Explanation:
