Healthcare providers collaborated with researchers in admini

Healthcare providers collaborated with researchers in administering particular pain management techniques with specialized magnets. Employ a 0.05 significance level to test the claim that those treated with magnets illustrate a greater reduction in pain than those given a placebo. Sample means and standard deviations are included with the data below. ( 18 points )

Reduction in in levels following magnet treatment:   n = 20, x_ave = 0.49, s = 0.96

Reduction in in levels following magnet treatment:   n = 20, x_ave = 0.44, s = 1.4

Does it appear that the magnets might be effective if the sample sizes are larger?

Does it appear that the magnets are effective in treating back pain?

Construct a 90% CI estimate of the difference between the mean reduction in pain for those treated with magnets, and the mean reduction in pain for those given a sham treatment. From these results, does it appear that the magnets are effective in reducing pain? Justify your answers.
