Question

) parameter D) significance level 3 The alternative hypothesis, Ha is al o called "Status Quo Hypothesis." (A) True (B) False 4 The null hypothesis, Ho, is also called "Rescarch Hypothesis." (A) True (B) False 5. What decision can be made at 0.05 significance level? (A) Reject Ho because the test statistic falls in the rejection region (B) Fail to reject Ho because the test statistic doesn't fall in the rejection region 6. The Power of a hypothesis test is the probabilt (A) 1- of rejecting a true null hypothesis (B) 1- of failing to reject a true null hypothesis (C) 1- of rejecting a true null hypothesis (D) 1- of rejecting a false null hypothesis 7. Which of the following is NOT a true statement about error in hypothesis testing? (A) A type II error is making the mistake of failing to reject the null hypothesis when it is actually false. (B) A type I error is making the mistake of rejecting the null hypothesis when it is actually false (C) The symbol represents the probability of a type I error (D) A type I error is making the mistake of rejecting the null hypothesis when it is actually true. 8. Which of the following is NOT a criterion for making a decision in a hypothesis test? (A) If a confidence interval does not include a claimed value of a population parameter, the decision is to reject the null hypothesis (B) If P-value s , the decision is to reject the null hypothesis. Otherwise, we fail to reject the null hypothesis (C) If the test statistic falls within the critical region, the decision is to reject the null hypothesis. (D) None of the above 9 The A) conditional hypothesis contains the "=" sign. B) alternative C) null D) explanatory

Explanation / Answer

Result:

3). False

4). False

5). A.

6). D. 1- of rejecting a false null hypothesis.

7). B). the type I error is making mistake of rejecting the null hypothesis when it is actually false. ( this is not true statement).

8).

C). if the test statistic falls within the critical region, the decision is to reject the null hypothesis.
