All of the following are TRUE about t-distributions and z-distributions EXCEPT:
The t- and z-distributions are very similar in value for very large sample sizes (like n > 1000)
For the same sample size "n", the t-score will always be greater than the z-score.
Inference for means always use a Z-distribution and proportions always use a t-distribution
For small sample sizes, the t-distribution is much more wider than the - distribution.
