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 th two arms. What can be concluded? Right arm Left arm 148 179 OA. Ho Hd #0 H₁: Hd > 0 c. Ho: Hd=0 H₁: Hd #0 Identify the test statistic. t= 148 137 164 190 133 146 In this example, Hd is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the measurement from the right arm minus the measurement from the left arm. What are the null and alternative hypotheses for the hypothesis test? 139 D 143 (Round to two decimal places as needed.) CE B. Ho Hd #0 H₁: d=0 D. Ho: Hd=0 H₁ <0 4
