Question

Magnet Problem
Researchers conducted a study to determine whether magnets are effective in treating back pain. The results are shown in the table below. The results are a measure of reduction in back pain. Assume that the two samples are independent random samples.

	Treatment	Sham
μ	μ₁	μ₂
n	21	21
x̄	0.59	0.45
s	0.52	1.43

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.

State the claim, null, and alternative hypothesis.
