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 0.05 significance level to test for a difference between the
measurements from the two arms. What can be concluded?

In this example, . 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 A. Ho: Ha = 0
O B. Ho: Hd #0
0 = Prt :H
O D. Ho: Hd =0

O C. Ho: Ha 0
Identify the test statistic.

(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
than the significance level,
the null hypothesis. There
sufficient evidence to support the claim of a difference in
measurements between the two arms.
