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. a a lt\" 1.0 |4.3] 104 1.0/8.0) w4 2.0|5.5| * 2.0/6.7) g x x a x x 3.068] - 7 * 3.0 | 7.7 7 x 40/46] x 40/59] x 5 x 5 5.0 |49) || x x * 5.0 |69) | x x 6.0/8.0; 31 6.0/4.5) st x 7.0/5.1) 2+ 7.0/5.2) 2+ 1+ lt 8.0 | 7.1 x 8.0 |3.4 x 90 89 2 4 5 6 7 8 9 Will 90 46 263 45 6 7 8 Will 10.0|7.6| Figure 1 10.0} 2.5| Figure 2 10/70] w+ x x 1.0 |10.0| w+ x 20/97) * \" 20/90; \"7 * g a x 3.0/3.8] sh x 3.0 | 8.0 x 40/90] x % 40/70] x 5 4 5 x 5.0} 5.2) | 5.0| 6.0} || x 60;21) sh 6.0} 5.0] 31 x 7.0/5.9) 2 * 7.0) 4.0) 2) x 1+ lt x 8.0 | 10.0 " 8.0 | 3.0 m 90 49 2634 5 6 7 8 Will 90 20 2 4 5 6 7 8 9 Will 10.0| 8.3 | Figure 3 10.0| 1.0 | Figure 4 Answer the following questions about the relationships between pairs of variables and the values of r, the sample correlation coefficient. The same response may be the correct answer for more than one question. () Correlation and Simple Linear Regression Linear relationship and the sample correlation coefficient (Choose one) (b) For which data set is the sample correlation coefficient r closest to 0? (Choose one) v (c) For which data set is the sample correlation coefficient r equal to 1? (Choose one) v (d} Which data set indicates the strongest positive linear relationship between its two variables? (Choose one) v
