Question 17 need all the responds

A study was conducted to determine whether magnets were effective in treating pain. The values represent measurements of n X S pain using the visual analog scale. Assume that both samples are independent simple random samples from populations having Sham 20 0.44 1.44 normal distributions. Use a 0.05 significance level to test the claim that those given a sham treatment have pain reductions that Magnet 20 0.47 0.97 vary more than the pain reductions for those treated with magnets. What are the null and alternative hypotheses? OA. HO: 01 = 02 OB. Ho: 01 H1 01 H1 6 -02 OC. Ho 01 = 02 OD. Ho: 01 -52 NT H 1 : 01>02 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?
