Below are four bivariate data sets and the scatter plot for each. (Note that each scatter plot is displayed on the same scale.) Each data set is made up of sample values drawn from a population. 1.0 3.7 10- 1.0 8.0 2.0 5.9 10 2.0 6.6 3.0 6.9 3.0 7.5 7. 4.0 4.8 4.0 5.9 6- 6- 34 5.0 5.4 5.0 6.5 4- 6.0 4.6 6.0 8.6 24 7.0 5.3 24 5.2 7.0 8.0 6.8 89 10 11 8.0 3.4 $9 10 11 9.0 9.1 9.0 4.2 Figure 2 Figure 1 10.0 7.5 10.0 2.9 1.0 10.0 B.2 - 104 2.0 4.8 1.0 104K 2.0 9.0 3.0 8.0 3.0 9.5 4.0 7.0 4.0 5.8 5.0 2.1 5.0 6.0 6.0 5.0 6.0 4.7 34 7.0 4.0 7.0 8.8 8.0 3.0 8.0 3.6 9.0 2.0 Figure 4 9.0 9.1 Figure 3 10.0 1.0 10.0 7.2 2onse mau he thocorractancwerfor more than one.ariactinn oolo oS ololo lo0 www-awn.aleks.com/alekscgi/x/Isl.exe/1o_u-lgNslkr7j8P3jH-IBGBIH_OB3uhhqwxlXoS5SIQhuX6YjFjUgDFRvhXH9relMzlvv23_Pp32u8TfsHP_jUm65AJtEEbAJNv_rSkUZovRdKKoq?1oBw7QYjlbavbSPXtx-YCjsh_7mMmrc O CORRELATION AND SIMPLE LINEAR REGRESSION Emmanuel V Linear relationship and the sample correlation coefficient 3.2 1.0 10.0 11 11 10 10- 2.0 9.0 2.0 4.8 3.0 8.0 3.0 9.5 4.0 5.8 4.0 7.0 5.0 6.0 5.0 2.1 6.0 4.7 3. 6.0 5.0 3-+ 2. 7.0 4.0 7.0 8.8 An + 12 345 8.0 3.6 8.0 3.0 6 7 8 910 11 0 1 2 3 45 6 7 8 9 10 11 9.0 9.1 9.0 2.0 Figure 4 Figure 3 10.0 1.0 10.0 7.2 Answer the following questions.
