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 Left Arm 145 184 138 174 117 192

In this example,μd is the
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
Identify the test statistic.
t=
(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 less/greaterthan the significance level,rejectfail to reject the null hypothesis. There is/is not sufficient evidence to support the claim of a difference in measurements between the two arms.
