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. x y 11 - u V 1.0 8.2 10 - X X 1.0 1.0 10 X X 2.0 4.9 2.0 2.0 X 8 - X 3.0 10.1 X 3.0 3.0 X 4.0 6.0 X 4.0 4.0 X 1.9 X X 5.0 X 5.0 5.0 X X 6.0 4.9 6.0 6.0 X 7.0 9.3 X 7.0 7.0 2_ 1 - X 8.0 3.8 8.0 8.0 9.8 9 10 11 0 9.0 9.0 9.0 6 7 8 9 10 11 10.0 7.0 Figure 1 10.0 10.0 Figure 2 W 11 - m n 11 - 1.0 2.8 10 - 1.0 7.6 10- 2.0 4.0 9 - X 8 - X 2.0 9.0 8+ 3.0 3.5 X X 3.0 7.2 X X X X X 4.0 6- X 4.0 15.5 X X X 5.0 7.6 5- X 5.0 4.3 X X X X 6.0 X 3 - X 6.0 5.0 7.0 5.7 2 - 7.0 4.2 8.0 7.6 8.0 7.4 9.0 6.8 2 3 4 3 6 7 8 5 10 1 9.0 5.6 3 6 7 8 9 10 11 10.0 8.3 Figure 3 10.0 4.0 Figure 4 Answer the following questions.
