The StudentSurvey dataset includes information on the number of hours a week students say they exercise and the number of hours a week students say they watch television.
(a) What would a positive relationship between these two variables imply about the way students spend their time? What would a negative relationship imply?
(b) For each corner of the scatterplot of these two variables shown in Figure 2.60 (top left, top right, bottom left, bottom right), describe a student whose daily habits place him or her in that corner.

Figure 2.60

(c) There are two outliers in this scatterplot. Describe the student corresponding to the outlier on the right. Describe the student corresponding to the outlier on the top.
(d) The correlation between these two variables is r = 0.01. What does this correlation tell you about the strength of a linear relationship between these two variables?
