### 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.

1 The results below are based on a sample of 20 employees selected to study the relationship between income (Y, in $1,000) and four variables: Age (X1, in years), work experience (X2,in years), number of years of education (X3), and number of past jobs (X4). Find the lower end point in a 90% confidence interval for the change in the mean salary in dollars, for a unit change in number of past jobs, assuming that the other predictors remain unchanged.

Which of the following is not true when using the confidence interval method for testing a claim about u when a is unknown? Choose the correct answer below. OA. The P-value method, the traditional method, and the confidence interval method are equivalent and yield the same results. OB. For a one-tailed hypothesis test with a 0.05 significance level, one must construct a 90% confidence interval. OC. The P-value method and the classical method are not equivalent to the confidence interval method in that they may yield different results. OD. For a two-tailed hypothesis test with a 0.05 significance level, one must construct a 95% confidence interval.
