A matched pairs experiment is carried out, yielding the following data:

nD=72,x¯D=2.8,sD=8.5

Is there evidence, at an α=0.06 level of significance, to conclude that there is a difference between the two sets of measurements? Carry out an appropriate hypothesis test, filling in the information requested.

A. The value of the standardized test statistic: 

B. The p-value is 

C. Your decision for the hypothesis test:  A. Reject Ha.  B. Do Not Reject H0.  C. Do Not Reject Ha.  D. Reject H0.
