When testing the difference between two population proportions, a t test may be used.Group of answer choicesTrueFalse

For testing the difference between two population proportions, the pooled proportion estimate should be used to compute the value of the test statistic when the:Group of answer choicespopulations are normally distributed.sample sizes are large enough.null hypothesis states that the first population proportion is half of the second.null hypothesis states that the two population proportions are equal.

A t test for testing the difference between two population means from two independent samples is the same as the t test to test the difference of two population means in a matched pairs experiment.Group of answer choicesTrueFalse
