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

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?

Identify the test statistic.

​(Round to two decimal places as​ needed.)

Identify the​ 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.
