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 0.01 significance level to test for a difference between the measurements from the two arms. What can beconcluded?

Right arm

150

138

119

129

132

Left arm

172

167

192

151

148

In thisexample, d is the mean value of the differences d for the population of all pairs ofdata, 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 hypothesistest?

A.

H0: d0

H1: d>0

B.

H0: d=0

H1: d<0

C.

H0: d0

H1: d=0

D.

H0: d=0

H1: d0

Identify the test statistic.

Identify the P-Value

What is the conclusion based on the hypothesistest?

Since the P-Value is less or greater than the significancelevel, reject or fail to reject the null hypothesis. There is or is not sufficient evidence to support the claim of a difference in measurements between the two arms.
