A. The standard normal is a special case of the t-distribution, the square of which is a special case of the F-distribution
B. Since the three distributions are related, the 5% critical values from each will be the same
C. Asymptotically, a given test conducted using any of the three distributions will lead to the same conclusion
D. The normal and t- distributions are symmetric about zero while the F- takes only positive values
