Wait, isn't the estimated mean divided by the estimated standard deviation supposed to have a normal distribution? I'm so confused right now.

Hmm, this question is a bit tricky. I think the answer is C, since the estimated mean divided by the estimated standard deviation should follow a t-distribution.
