I also need to know test statistic, p wave, conclusion, confidence interval suitable to test the hypothesis in part A . Does the confidence interval support the conclusion found in the hypothesistest? Because it contains___?

Researchers conducted a study to determine whether magnets are effective in tre as measured using the visual analog scale, and the results shown below are among the results obtained in the study Higher scores correspo levels Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assomer ulation standard deviations are equal Complete parts (a) to (c) below. Reduction in Pain Level After Magnet Treatment (),) - 25 X -0 56. 5-093 Reduction in Pain Level After Sham Treatment ,) = 25, x -0 47 S=1 31 a. Use a 0 05 significance level to test the claim that those treated with magnets have a greater mean reduction in pain than those given a sham treatment (similar to a placebo). What are the null and alternative hypotheses? OA. HO TUZ OC. H, P. F12
