How do I find the test statistic, p value and construct the confidence interval appropriate for the hypothesis test?

Researchers conducted a study to determine whether magnets are effective in treating back pain. Pain was measured using the visual analog scale, and the results shown below are among the results obtained in the study. Higher scores correspond to greater pain levels. Assume that the two samples are independent simple random samples selected from normally distributed populations, and do not assume that the population standard deviations are equal. Complete parts (a) to (c) below. Reduction in Pain Level After Magnet Treatment (H, ): n = 19, x = 0.43, s = 1.02 Reduction in Pain Level After Sham Treatment (H2): n = 19, x = 0.34, s = 1.39 UL. MO: MISH2 O U. NO: P1 - H2 Hy: H1 2 H2 Hy: M1 - H2 The test statistic, t, is . (Round to two decimal places as needed.) The P-value is . (Round to three decimal places as needed.) State the conclusion for the test. Fail to reject the null hypothesis. There is not sufficient evidence to support the claim that those treated with magnets have a greater mean reduction in pain than those given a sham treatment. b. Construct a confidence interval appropriate for the hypothesis test in part (a). (Round to two decimal places as needed.)
