study was conducted to determine whether or not magnets were effective in treating lower back pain. The control group was given a placebo treatment. Pain was measured using the visual analog scale. Reduction in pain level for the 100 patients given the magnet treatment was an average of 0.49, and a standard deviation of 0.96. Reduction in pain level for the 100 patients given the plabo treatment was an average of 0.44, and a standard deviation of 1.4. Test at the 95% confidence level to determine whether or not the magnet therapy was effective. Use a two tailed test of hypothesis and the p-value to form your conclusion. Show and number all of the steps.
