Hypothesis Tests of Claims About Variation. In Exercises 716, test the given claim. Assume that both samples are independent simple random samples from populations having normal distributionsMagnet Treatment of Pain Researchers conducted a study to determine whether magnets are effective in treating back pain, with results givenbelow (based on data from Bipolar Permanent Magnets for the Treatment of Chronic Lower Back Pain: A Pilot Study, by Collacott, Zimmerman,White, and Rindone, Journal of the American Medical Association, Vol. 283, No. 10). The values represent measurements of pain using the visualanalog scale. Use a 0.05 significance level to test the claim that those given a sham treatment (similar to a placebo) have pain reductions that varymore than the pain reductions for those treated with magnets.Reduction in Pain Level After Sham Treatment: n = 20 , x = 0.44 , s = 1.4 Reduction in Pain Level After Magnet Treatment: n = 20 , x = 0.49 , s =0.96
