Question

(Less/greater). (Reject/fail to reject). (Is not/is) 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 nomal. Use a 0.01 significance level to test for a difference between the measurements from the two arms. What can be concluded? Right arm 144 140 135 135 133 Left arm 171 177 191 140 153 In this example, Pa 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? Identify the test statistic te (Round to two decimal places as needed ) Identify the P-value P-value= (Round to three decimal places as needed ) What is the conclusion based on the hypothesis test? Since the P-value is w/ than the significance level. Y the nulf hypothes's There sulffcient evidence to support the claim of a difference in measurements between the two arms Click to select your answers)

Explanation / Answer

Null and alternate hypothesis : Option D

p-value = 0.03455

since the p-value is greaer than the significance level. Fail to reject the null hypothesis. there are not sufficient evidence to support the claim of a difference in measurements between the two arms.
