Three statistics classes (50 students each) took the same test. Shown below are histograms of the scores for the classes. Use the histograms to answer the question. Which class do you think performed better on the test? a.Class 2, because it has different mean and median and 70% of class 2 scored at or above the medians of 1 and 3. b. Class 2, because it has the highest median and 70% of class 2 scored at or above the medians of 1 and 3. c. Class 1, because it has the smallest median and 70% of class 1 scored at or above the medians of 2 and 3. d. Class 3, because 74% of class 3 scored at or above the medians of 1 and 2. e. Class 2, because it has the highest median and 50% of class 2 scored at or above the medians of 1 and 3.
