### Study on the Effectiveness of Magnets for Back Pain Treatment**Introduction:**A study was conducted to test the effectiveness of magnet treatments for back pain. Thirty-five patients were given a treatment both with magnets and with a sham (placebo) treatment.**Data Collection:**Pain was measured on a scale from 0 (indicating no pain) to 100 (indicating extreme pain). The results were as follows:- Patients given magnets had a mean pain score of 11.3 with a standard deviation of 11.1.- Patients given the sham treatment had a mean pain score of 22.4 with a standard deviation of 18.2.**Tasks:**a. **Construct the 95% Confidence Interval** for the mean pain score for patients given the magnet treatment.b. **Construct the 95% Confidence Interval** for the mean pain score for patients given the sham treatment.c. **Comparison and Analysis:** - Compare the results. Does the treatment with magnets appear to be effective? - **Options:** - A. Since the confidence intervals do not overlap, it appears that the magnet treatments are more effective than the sham treatments. - B. Since the confidence intervals overlap, it appears that the magnet treatments are no more effective than the sham treatments. - C. Since the confidence intervals do not overlap, it appears that the magnet treatments are no more effective than the sham treatments. - D. Since the confidence intervals overlap, it appears that the magnet treatments are less effective than the sham treatments.**Conclusion:**Based on the analysis of the confidence intervals, determine if the magnet treatment significantly reduces pain compared to the sham treatment. Use the result to conclude the effectiveness of the treatment.

The results obtained above were primarily due to the mean for the third treatment being noticeably different from the other two sample means. For the following data, the scores are the same as above except that the difference between treatments was reduced by moving the third treatment closer to the other two samples. In particular, 3 points have been subtracted from each score in the third sample. Before you begin the calculation, predict how the changes in the data should influence the outcome of the analysis. That is, how will the F-ratio for these data compare with the F-ratio from above?

There are many ways to measure the reading ability of children. Research designed toimprove reading performance is dependent on good measures of the outcome. Onefrequently used test is the DRP, or Degree of Reading Power. A researcher suspects that themean score µ of all third- graders in Henrico County Schools is different from the nationalmean, which is 32. To test her suspicion, she administers the DRP to an SRS of 44 HenricoCounty third-grade students. The distribution of scores is summarized in the Minitab outputbelow: MEAN STDEV SEMEAN MIN Q1 MEDIAN Q3MAXDRP 35.09 11.19 1.69 14.00 26.00 35.00 44.0054.00 Construct a 90% confidence interval to estimate the mean DRP score in Henrico CountySchools.
