Construct a scatter plot, find the value of the linear correlation coefficient r,
Question Description
Listed below are baseball team statistics, consisting of
the proportions of wins and the result of this
difference: Difference (number of runs scored)

(number of runs allowed). The statistics are from a
recent year, and the teams are NY
—
Yankees, Toronto, Boston, Cleveland, Texas, Houston, San
Francisco, and Kansas City.
Difference 163, 55 –5, 88, 51, 16, 214
Wins 0.599, 0.537, 0.531, 0.481, 0.494, 0.506, 0.383
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?
