Scenario 3: You are testing the effect of drug X on fly activity. For flies not treated with drug X, you measure an average of 11 AUs (activity units) with a standard deviation of 2 AUs (n = 13). For flies treated with drug X, you measure an average of 24 AUs with a standard deviation of 6 AUs (n = 18). What is the between-group variability in this study? (hint: Group Workshop Significance Testing will help!) Your answer will be a whole number without decimal points
