- ZProportion2Test[<Sample Proportion 1>,<Sample Size 1>,<Sample Proportion 2>,<Sample Size 2>,<Tail>]
- Performs a test of the difference between two population means 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
- "≠" = difference in population proportions ≠ 0
- Results are returned in list form as {P value, Z test statistic}.
