• Looking at the output below, do either of these variables appear to have outliers? If so, what are the values of the outlier?
• What do you suggest should be done about the outlier(s)?

2. Explain step-by-step how you would compute histograms that also include the plot of the normal curve on them for the two variables: exam and computer. What do these tell you about the distributions of each variable? (4 points)
