E Test: Week 1 Test ... Question 11 This Test: 100 pts possible Submit Test A study was conducted to determine whether magnets were effective in treating pain. The values represent measurements n X S of pain using the visual analog scale. Assume that both samples are independent simple random samples from Sham 20 0.43 1.42 populations having normal distributions. Use a 0.05 significance level to test the claim that those given a sham treatment Magnet 20 0.46 0.92 have pain reductions that vary more than the pain reductions for those treated with magnets. What are the null and alternative hypotheses? OA. Ho: 02 = 02 OB. Ho: 02 =03 H1: 07 5 02 H1: 09 # 02 OC. Ho: 02 = 03 OD. Ho: 02 # 0? H1: 0-> 02 H1: 09 = 03 Identify the test statistic. F=(Round to two decimal places as needed.) Use technology to identify the P-value. The P-value is . (Round to three decimal places as needed.) What is the conclusion for this hypothesis test? O A. Fail to reject Ho. There is insufficient evidence to support the claim that those given a sham treatment have pain reductions that vary more than those treated with magnets. O B. Fail to reject Ho. There is sufficient evidence to support the claim that those given a sham treatment have pain reductions that vary more than those treated with magnets. O C. Reject Ho. There is sufficient evidence to support the claim that those given a sham treatment have pain reductions that vary more than those treated with magnets. O D. Reject Ho. There is insufficient evidence to support the claim that those given a sham treatment have pain reductions that vary more than those treated with magnets
