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
0.01 significance level to test for a difference between the
measurements from the two arms. Identify the test statistic and
p-value.
RIGHT ARM 146 136 114 130 136
LEFT ARM 165 177 187 146 135
A.
T = -3.07, p-value = 0.037
B.
T = -2.32, p-value = 0.081
C.
T = -1.93, p-value = 0.127
D.
T = -4.01, p-value = 0.016
