The Z-test is the appropriate statistical test for hypotheses about proportions with two large samples. It is used to compare two population proportions when the sample size is large and the standard deviation of the population is known or can be estimated. The chi-square test is used for comparing observed and expected frequencies in contingency tables. The t-test is used for comparing means of two groups, while ANOVA is used for comparing means of more than two groups.
