Question Help A study was conducted to determine whether magnets were effective in treating pain. The values the visual analog scale. Assume that both samples are s n 1.26 20 0.42 t m ees Sham ple random samples from populations having normal distributions. Use a 0.05 0.92 0.49 Magnet 20 significance level to test the claim that those given a sham treatment have pain reductions that vary more than the pain reductions for those treated with magnets. What are the null and alternative hypotheses? OB. Ho: Hy: 0 > OD. Ho: 02 H: 0 OA. Ho:02 OC. Ho: o02 Hy: 0< Identify the test statistic. (Round to two decimal places as needed.) F Use technology to identify the P-value. (Round to three decimal places as needed.) The P-value is What is the conclusion for this hypothesis test? O A. Fail to reject Hn. 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 B. 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 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. Fail to reject Ho- There is insufficient evidence support the claim that those given a sham treatment have pain reductions that vary more than those treated with magnets Click to select your answer(s).
