At a sample size of infinity, the t distribution:
A) is unreliable.
B) has a standard deviation of 0.
C) is identical to the z distribution.
D) has a standard deviation of 0.50.

Question

Quizplus · Accepted Answer

As the sample size approaches infinity, the t distribution converges to the standard normal distribution (z distribution), which has a mean of 0 and a standard deviation of 1. Therefore, option C is correct. Options A, B, and D are incorrect as they do not correctly describe the behavior of the t distribution at infinite sample size.
