A study was conducted to determine whether magnets were effective in treating pain The values represent measurements of pain using the visual analog scale Assume that both samples are independent simple random samples from populations having normal distributions Use a 0 05 significance level to test the claim that those given a shamn treatment have pain reductions that vary more than the pain reductions for those treated with magnets What is the conclusion for this hypothesis test Sham Magnet n 20 20 X 0 43 0 49 S 1 57 0 91 OA 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 OB 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 OC Fall 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 OD Fall 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
