Question 2 of 20 (1 point) | Question Attempt: 1 of Unlimited 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. 11 10 8.0 10- 1.0 8.2 10- X 2.0 4.8 2.0 7.1 3.0 10.0 X 3.0 7.7 4.0 5.8 4.0 6.2 5.0 20 5.0 6.9 X 6.0 50 6.0 4.5 X 7.0 9.2 X 7.0 4.9 8.0 4.1 8.0 3.4 9.0 9.4 9.0 4 5 10.0 7.0 Figure 1 10.0 2.9 Figure 2 1.0 2.8 10- 1.0 3.8 LO- 2.0 3.7 2.0 5.9 3.0 3.4 3.0 74 X 4.0 5.1 X 4.0 5.0 5.0 4.6 5.0 5.0 X X 6.0 6.8 X 6.0 7.9 7.0 5.6 7.0 5.5 80 7.8 8.0 6.9 9.0 7.3 9.0 9.0 10.0 7.7 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.
