2.12 Make a scatterplot.

(a) Make a scatterplot similar to Figure 2.1 for the laundry detergent data.

(b) Two of the laundry detergents are gels. These products are made by the same manufacturer, and one of them has an additive for stain removal. The ratings and prices per load are the same; the rating is 46 and the price is 13. Mark the location of these gels on your plot.

(c) Cases with identical values for both variables are generally indistinguishable in a scatterplot. To what extent do you think that this could give a distorted picture of the relationship between two variables for a data set that has a large number of duplicate values? Explain your answer.
