(c) Determine the linear correlation coefficient between weight and length. The linear correlation coefficient between weight and length is r = 0.720'. (Round to three decimal places as needed.) (d) Does a linear relation exist between the weight of the bear and its length? Because the correlation coefficient is positive and the absolute value of the correlation coefficient. 0,720 , is greater than the critical value for this data set. 0.576. a positive linear relation exists between the weight of the bear and its length. (Round to three decimal places as needed.)
