Question

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 0.10 significance level to test for a difference between the measurements from the two arms. What can be concluded? Right arm 144 138 138 138 133 Left arm 173 169 188 146 144 In this example, μd 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? A. H0: μd≠0 H1: μd>0 B. H0: μd≠0 H1: μd=0 C. H0: μd=0 H1: μd<0 D. H0: μd=0 H1: μd≠0

Right arm	144	138	138	138	133	 
Left arm	173	169	188	146	144	
In this example, 
μd 
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?
 
A.
H0: 
μd≠0
H1: 
μd>0
 
B.
H0: 
μd≠0
H1: 
μd=0
 
C.
H0: 
μd=0
H1: 
μd<0
 
D.
H0: 
μd=0
