Which of the following is NOT a criterion for making a decision in a hypothesis test? Choose the correct answer below.

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

B.) If a confidence interval does not include a claimed value of a population parameter, the decision is to reject the null hypothesis.

C.) If the P-value is less than 0.05, the decision is to reject the null hypothesis. Otherwise, we fail to reject the null hypothesis.

 

Forest bathing, also called Shinrin-yoku, is the practice of taking short, leisurely walks in a forest to enhance positive health. To test the usefulness of this practice, the time forest bathing per day was recorded among eight patients with depression who subsequently showed a marked reduction in their symptoms over the last week. The data are given in the table.

Time Spent in the Forest (in hours)
4.3
4.8
5.1
3.7

(a) Find the confidence limits at a 95% CI for this sample. (Round your answers to two decimal places.) 
(No Response) to (No Response) hours per day 

(b) Suppose the null hypothesis states that the average time spent forest bathing among patients is 3.5 hours per day. What would the decision be for a two-tailed hypothesis test at a 0.05 level of significance?
    

Identify the null hypothesis, alternative hypothesis, test statistic, P-value or critical value(s), then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. A simple random sample of front-seat occupants invol ved in car crashes is obtained. Among 2823 occupants not wearing seat belts, 31 were killed. Among 7765 occupants wearing seat belts, 16 were killed. We want to use a 0.05 significance level to test the claim that seat belts are effective in reducing fatalities. Test the claim using a hypothesis test.
