Question 12: give the rejection region. The mean of a population is assumed to be 5000. However, itis also believed the mean is not 5000. A sample of size 49 fromthe population is considered. Assume a calculated samplemean of 5100 and a standard deviation of 100. At the 5%significance level we will determine if the null hypothesis willbe rejected. Give the null and alternative hypotheses. Give the rejection region.z less than -1.64O z greater than 1.64O Two-Tailed, z less than -1.96 and greater than 1.96O Two-Tailed, z less than -1.64 and greater than 1.64

Given : Claim : The mean is not 5000.

Answered: The mean of a population is assumed to…

QUESTION 12 Are beer (B), wine (W), and liquor (L) equally favored by Americans as the alcoholic drink they consume most often? A 2016 Gallup survey interviewed a random sample of American adults about their alcohol consumption and preferences. Of the 647 non-abstainers who answered the question about which beverage beer, wine, or liquor they consume most often, 293 selected beer, 218 selected wine, and the remaining 136 selected liquor. What is the p-value and decision rule for the test using a significance level of 0.05? O p-value = 1.000, we reject Ho. O p-value = 0.000, we reject Ho. O p-value = 1.000, we fail to reject Ho. O p-value = 0.000, we accept Ho-

PLEASE ONLY SELECT THE ANSWERS AS SHOWN FOR THE MULTIPLE CHOICE, SUCH AS OPTION 1, 2, ETC. 1) A 9-year-old girl did a science fair experiment in which she tested professional touch therapists to see if they could sense her energy field. She flipped a coin to select either her right hand or her left hand, and then she asked the therapists to identify the selected hand by placing their hand just under her hand without seeing it and without touching it. Among 297 trials, the touch therapists were correct 116 times. Use a 0.05 significance level to test the claim that touch therapists use a method equivalent to random guesses. Do the results suggest that touch therapists are effective? Identify the null and alternative hypotheses for this test. Choose the correct answer below. A. H0: p=0.5 H1: p>0.5 B. H0: p=0.5 H1: p≠0.5 C. H0: p≠0.5 H1: p=0.5 D. H0: p=0.5 H1: p<0.5 2) Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is…

Show all your work. Indicate clearly the methods you use, because you will be scored on the correctness of your methods as well as on the accuracy and completeness of your results and explanations. Patients experiencing symptoms of a heart attack are routinely transported to a hospital in an ambulance. In a study of a new treatment thought to reduce damage to the heart, patients experiencing symptoms of a heart attack were randomly assigned to one of two groups. During transportation to the hospital, patients in one group received standard care, and patients in the other group received the new treatment consisting of standard care and the application of a blood pressure cuff. The response variable measured for each patient was a number between 0 and 1, referred to as the myocardial salvage index (MSI). A higher MSI value indicates a more positive outcome for the patient. Summary statistics for the MSI responses of the two groups are shown in the table below. Do the data provide…
