Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left arms of the same woman. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Use a 0.10 significance level to test for a difference between the measurements from the two arms. Identify the test statistic and p-value.

	A.	T = -4.01, p-value = 0.016
	B.	T = -3.07, p-value = 0.037
	C.	T = -1.93, p-value = 0.127
	D.	T = -2.32, p-value = 0.081
