Assume that you are running an experiment to test the hypothesis that caffeine enhances learning. You have set up a between-subjects design with three different treatment groups that differ in how much espresso each participant drinks before starting the task.The three groups, which you label A, B, and C, correspond to 1, 2, or 3 shots of espresso, respectively. The dependent variable is percent correct on the last block of learning trials.Thirtysubjects signed up for the experiment and they have beenrandomlyassigned totreatments groups while insuring that each group receives 10 subjects.Use the attached spreadsheet to answerthe questions.
