Question
Transcribed Image Text: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

H₁: Hd #0
OC. Ho: Hd = 0
H₁: Hd <0

In this example, Hd 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.
