Quizplus · Accepted Answer

In tests of differences between two percentages, researchers may have a specific direction in mind for the outcome of the analysis, and therefore may formulate directional hypotheses. For example, a researcher may hypothesize that one percentage is higher or lower than the other, rather than simply testing if they are different. Thus, option A) is the best choice for this question.
