Suppose that we wish to compare the means of two populations using paired observations. Suppose further that d ̅=3.125, sd=2.911, and n=8. The null hypothesis for the test, which is to be conducted at the 10% level of significance, is Ho: μd ≤ 0. What would be the decision rule for the test?
A. Reject Ho if the computed test statistic is ≤ 1.415.
B. Reject Ho if the computed test statistic is ≥ 1.415.
C. Reject Ho if the computed test statistic is > -1.415 or <>
D. Reject Ho if the computed test statistic is ≥ 1.415.
