For a data set of chest sizes​ (distance around chest in​ inches) and weights​ (pounds) of eleven anesthetized bears that were​ measured, the linear correlation coefficient is r=0.847. Use the table available below to find the critical values of r. Based on a comparison of the linear correlation coefficient r and the critical​ values, what do you conclude about a linear​ correlation view the table of critical values of r. What are the critical values of r?
