what is P-value? fail to reject or reject? is there sufficient evidence? confidence interval? does the confidence interval support the conclusion found with the hypothesis test?

Treatment Sham Researchers conducted a study to determine whether magnets are effective in treating back pain. The results are shown in the table for the H1 H2 treatment (with magnets) group and the sham (or placebo) group. The results are a measure of reduction in back pain. Assume that the two n 13 13 samples are independent simple random samples selected from normally distributed populations, and do not assume that the population X 0.53 0.42 standard deviations are equal. Complete parts (a) and (b) below. S 0.99 1.08 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. What are the null and alternative hypotheses? O A. Ho: H1 = H2 OB. Ho: H1

H2 The test statistic, t, is . (Round to two decimal places as needed.)
