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

 

Right arm

147

133

137

133

134

 

Left arm

176

178

190

143

134

 

In this​ example, μd 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?

Answer:
H0​: μd=0

H1​: μd≠0

 

**Identify the test statistic.

t=_______ ​(Round to two decimal places as​ needed.)
