Below are four bivariate data sets and their scatter plots. (Note that all of the scatter plots are displayed with the same scale.) Each data set is made up of sample values drawn from a population. 1.0 3.1 2.0 4.1 11-2 10- 84 3.0 3.7 7+ 6 4.0 5.2 5.0 4.6 6.0 6.7 7.0 6.1 8.0 7.6 9.0 7.0 10.0 8.2 Figure 1 4 3- X 11-' 104 9- 84 7- W 1.0 3.8 2.0 6.0 3.0 7.0 4.0 4.6 5.0 5.0 6.0 8.2 7.0 5.6 8.0 6.8 9.0 8.8 10.0 7.7 Figure 3 (Choose one) U V 1.0 8.0 10+ 2.0 7.1 3.0 7.6 4.0 6.3 (Choose one) 5.0 6.6 6.0 4.5 7.0 5.1 8.0 3.4 9.0 4.5 10.0 2.7 Figure 2 (a) For which data set is the sample correlation coefficient r closest to 1?
