W8Q3-Hi wonderful Bartleby team,

I need help to find the answers to the following: (Thanks in advance)

-Test Statistic

-The P-Value

-The last part where it says “b.Construct confidence intervals………”

Extracted text: 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 treatment (with magnets) group and the sham (or placebo) group. The results are a measure of reduction in back pain. 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) and (b) below. 16 16 0.55 0.96 xl 0.43 1.21 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? VA. Ho H1 =P2 H: P > P2 O B. Hg: H1 =H2 H: +42 OC. Ho: H P2 OD. Ho: H1

Extracted text: b. Construct a confidence interval suitable for testing the claim that those treated with magnets have a greater mean reduction in pain than those given a sham treatment. (Round to three decimal places as needed.)
