Quizplus · Accepted Answer

When testing the claim that one proportion is lower than another, we use a Z test for the difference between two proportions. The options A and D are incorrect as they test for the difference between two proportions without specifying which one is supposed to be lower. Option B is incorrect as it tests for the ratio of two variances, which is not related to the claim being tested.
