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 0.05significance 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. n x s Sham 20 0.41 1.27 Magnet 20 0.49 0.93 => Identify the test statistic. (Round to two decimal places as needed.) Use technology to identify the P-value. (Round to three decimal places as needed.) What is the conclusion for this hypothesis test? fail to reject/reject?
