REVIEWING PSYCHOLOGICAL STATISTICS CONCEPTSNote: All participants are randomly assigned to the groupsPROBLEM 3: The researcher conducted an experiment to determine whether temperature affects the test performance of college students. He matched the participants according to the GPA prior random assignment to the experimental and control group. One group took a 50-item test in a warm room while the other group took the same test in a cold room. He wanted to test the hypothesis at 0.05 level of significance.
