Multiple Choice

Imagine an experiment where the mean of the experimental group is 50 and the mean of the control group is 40. Given that the two means are obviously different, is it still possible for a researcher to say that the two groups are not significantly different?

A) Yes, the two groups could overlap so much that the difference was not significant.
B) Yes, if the difference was not predicted by the hypothesis.
C) No, because the two groups are clearly far too different for the difference to not be significant.
D) There is not enough information to answer this question.
