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? Right arm Left arm 144 177 134 115 133 136 D 165 189 156 150 C

In this example, "a 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
the left arm. What are the null and alternative hypotheses for the hypothesis test?
OA. Ho Hd #0
H₁ Hd=0
1
OC. Ho Hd #0
H₁ H₁0
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?
than the significance level,
Since the P-value is
the null hypothesis. There
O B. Ho Hd = 0
H₁: Hd <0
O D. Ho Hd=0
H₁ Hd #0
sufficient evidence to support the claim of a difference in measurements between the two arms.
