In an independent samples design the Hatfields had a mean score of 25 against a mean score of 26 for the McCoys. Low scores mean better performance. The researcher ran a two-tailed test with $\alpha$at .05. A t value of 1.99 was found.
A) If df = 40, the Hatfields are significantly better than the McCoys.
B) If df = 40, the McCoys are significantly better than the Hatfields.
C) If df = 120, the Hatfields and the McCoys are not significantly different.
D) If df = 120, the Hatfields are significantly better than the McCoys.
E) If df = 120, the McCoys are significantly better than the Hatfields.
