Quizplus · Accepted Answer

The question specifically mentions conducting a two-sample hypothesis test for proportions. Therefore, the appropriate test is the Z-test for differences in two proportions, which is represented by choice D. Choices A and C refer to tests for means, not proportions. Choice B refers to a chi-square test, which can also be used for testing differences in proportions, but the Z-test is the more commonly used test for this purpose.
