1. Multiple Choice. The scatterplots below display the relationship between x and y for nine different datasets. Note that the sample correlation for each case is displayed as well.

Use the plots and sample correlations from previous page to answer the following questions. Note: In order to get full credit on each of the questions below you need to check all options that apply. No partial credit will be given.

(e) Which datasets have a linear and strong relationship between x and y? List all that apply.

(f) Which datasets have a nonlinear relationship between x and y? List all that apply.

(g) Which dataset definitely contains outliers? List the best option.
