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 0.05 significance level to test for a difference between the measurements from the two arms. What can be​ concluded? -Identify the test statistic. -Identify the​ P-value. -What is the conclusion based on the hypothesis​ test? since the P-value is (less/ greater) than the significance level, (reject, accept) the null hypothesis. there (is/ is not) sufficient evidence to support the claim of a difference in measurements between the two arms.
