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

133
140

Part 1
In this example, mu Subscript d 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?
A.
Upper H 0: mu Subscript dnot equals0
Upper H 1: mu Subscript dgreater than0
B.
Upper H 0: mu Subscript dequals0
Upper H 1: mu Subscript dless than0
C.
Upper H 0: mu Subscript dequals0
Upper H 1: mu Subscript dnot equals0
D.
Upper H 0: mu Subscript dnot equals0
Upper H 1: mu Subscript dequals0
