Identify the test statistic. F- (Round to two decimal places as needed.) Use technology to identify the P-value. The P-value is D. (Round to three decimal places as needed.) What is the conclusion for this hypothesis test? O A. Reject Hg. 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. B. Fail to reject Hg. 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 Hg. 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.

Question
Transcribed Image Text: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 sham treatment have pain reductions that vary more
than the pain reductions for those treated with magnets.

What is the conclusion for this hypothesis test?
O A. 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 B. 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 C. Reject Hn. 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.
