Listed below are systolic blood pressure measurements (mm Hg) taken from the right and left ams 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 ams.

Transcribed Image Text: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 sarmple 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 ams. What can be concluded?
Right arm
Left arm

In this example, p, 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?
O B. H, Ha-0
O A. H, Pa0
H Pa=0
0> Prd H
OC Ho P. D
O D. H, H=0
Identify the test statistic.
