I'm not sure, but I think the test statistic for the hypothesis should be greater than 1, so I would go with D) 1.92 as well.

Haha, this question is a real head-scratcher. I bet the professor is just trying to confuse us. But I'll go with D just to be safe.

Hmm, the key seems to be figuring out the hypothesis being tested. Let's see, if the coefficient is less than 1, then the test statistic would be greater than 1. So, I'm going with D as well.
