Construct a scatter plot, find the value of the linear correlation coefficient r, and find the
critical values of r from
Table VI, Appendix A, p. A
-14, of your textbook Elementary Statistics
Use α = 0.05.is there sufficient evidence to conclude that there is a linear correlation between the
proportion of wins and the above difference?
