Question

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	18	18
x̄	0.57	0.42
s	0.54	1.46

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.

Determine the test statistic.
Round your answer to 2 decimal places.
