I'm so tired of these linear regression questions. Can we just skip to the part where we learn how to cook bacon in the microwave?

I'm not sure, but I think it might be C) -1.25. Can someone explain the rationale behind the test statistic?

Wait, is this a trick question? The absolute value of the t-statistic is what matters, not the sign. I think the correct answer is B) 2.5.

Yes, that's correct. The absolute value of the t-statistic is what we need to consider.

Actually, I think you're right. The sign doesn't matter for the t-statistic.

I agree with Myrtie, because a negative test statistic indicates the coefficient is less than zero.

Hmm, the test statistic for the hypothesis that the coefficient of x is zero against the alternative that x is less than zero is the t-statistic. Based on the output, I'd say the answer is D) -2.5.
