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.
