I think Lauran is correct, as the t-distribution is used when estimating the mean divided by the standard deviation.

I believe the estimated mean divided by the estimated standard deviation has a t-distribution, not the variance.

I agree with Art, because when observations are i.i.d. and normally distributed, the ratio follows a t-distribution.

Okay, let's see... If the random variables are i.i.d. and normally distributed, then the estimated mean divided by the estimated standard deviation should have a t-distribution. I think 'C' is the correct answer.

I'm pretty sure the estimated mean divided by the estimated variance has a Chi2-distribution. The standard deviation is just the square root of the variance, right?

That's right. The standard deviation is the square root of the variance.

The estimated mean divided by the estimated standard deviation has a t-distribution? That's a tough one. Let me think about it for a bit.
