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 Left arm 146 165 OAT= -4.01, p-value = 0.016 OB. T = -3.07, p-value = 0.037 OC. T = -2.32, p-value = 0.081 O D. T = -1.93, p-value = 0.127 136 114 130 136 177 187 146 135
