ZProportionTest[ <Sample Proportion>, <Sample Size>, <Hypothesized Proportion>, <Tail> ]
Performs a one sample Z test of a proportion using the given sample statistics. Hypothesized Proportion is the population proportion assumed in the null hypothesis. Tail has possible values "<", ">" , "≠". These specify the alternative hypothesis as follows.
"<" = population proportion < Hypothesized Proportion
">" = population proportion > Hypothesized Proportion
"≠" = population proportion ≠ Hypothesized Proportion
Results are returned in list form as {P value, Z test statistic}.
