(a) which data set is the sample correlation coefficient r closet to 10. (b) which data set indicates the strongest negative linear relationship between it's two variables (c) for which data set is the sample correlation coefficient r equal to -1. (d) for which data set is the sample correlation coefficient r closest to 1

Question a 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 8.5 1.0 2.8 10- X 2.0 4.9 2.0 3.8 3.0 10.3 3.0 3.2 4.0 4.0 5.2 X 5.0 5.0 42 215 6.0 5.3 X 6.0 6.7 7.0 9.4 X 7.0 5.7 8.0 3.6 8.0 79 90 9.4 9.0 6.8 10.0 7.0 Figure 1 10.0 8.1 Figure 2 m 1.0 8.0 1.0 4.4 10- 2.0 7.1 2.0 5.8 3.0 7.7 3.0 6.9 4.0 6.1 4.0 4.1 5.0 7.0 X X 5.0 4.9 Y 6.0 4.9 6.0 8.1 7.0 4.9 7.0 5.0 8.0 3.7 8.0 7.1 9.0 4.6 9.0 9.3 10.0 3.0 Figure 3 10.0 7.4 Figure 4 Answer the following questions about the relationships between pairs of variables and the values of r, the sample correlation coefficient.
