- ZProportion2Test[ <Sample Proportion 1>, <Sample Size 1>, <Sample Proportion 2>, <Sample Size 2>, <Tail> ]
- Performs a test of the difference between two population proportions using the given sample statistics. Tail has possible values "<", ">" , "≠". These specify the alternative hypothesis as follows.

- ">" = difference in population proportions > 0
- "≠" = difference in population proportions ≠ 0
- Results are returned in list form as {Probability value, Z test statistic}.
