The test statistic of z=2.13 is obtained when testing the claim that p> 0.8. a. Identify the hypothesis test as being two-tailed, left-tailed, or right-tailed. b. Find the P-value. c. Using a significance level of a = 0.10, should we reject Ho or should we fail to reject Ho? Click here to view page 1 of the standard normal distribution table. Click here to view page 2 of the standard normal distribution table. a. This is a test. b. P-value = D (Round to three decimal places as needed.) c. Choose the correct conclusion below. O A. Reject Ho. There is not sufficient evidence to support the claim that p> 0.8. B. Fail to reject Ho. There is not sufficient evidence to support the claim that p> 0.8. OC. Reject Ho. There is sufficient evidence to support the claim that p> 0.8. O D. Fail to reject Ho. There is sufficient evidence to support the claim that p> 0.8.

Describe a study in which you can use both nonparametric and parametric statistics. A researcher has participants expecting to receive either painful or mild electrical shocks during a study wait in a quarter-full waiting room with other participants. He then measures whether they choose to sit next to other participants or if they sit far away on their own. What is the best test to run for this study and why?
