The accompanying data gives the volume, in cubic feet, and diameter at breast height, in inches, for 70 shortleaf pines. a. Decide whether use of the linear correlation coefficient as a descriptive measure for the data is appropriate. b. If appropriate, obtain the linear correlation coefficient. c. If appropriate, interpret the value of r in terms of the linear relationship between the two variables. Click the icon to view the volume and Diameter data values. a. The linear correlation coefficient as a descriptive measure for the data V appropriate because b. Select the correct choice and, if necessary, fill in the answer box to complete your choice. Volume and Diameter data O A. The linear correlation coefficient is (Round to three decimal places as needed.) O B. The linear correlation coefficient as a descriptive measure for the data is not appropriate c. Choose the correct answer below. Volume Diameter (x) (y) 2.5 4.4 7.1 4.6 7 O A. There appears to be a strong negative linear association between the two variables. O B. There appears to be a weak positive linear association between the two variables. O C. There appears to be a strong positive linear association between the two variables. OD. There appears to be a weak negative linear association between the two variables. O E. The linear correlation coefficient as a descriptive measure for the data is not appropriate. 5 5.1 8.5 7.2 4.7 5.2 8.5 10.3 11.8 5.1 5.2 5.2 5.5 5.5 5.6 5.9 5.9 7.5 7.6 7.6 7.8 Volume Diameter (x) (y) 25.5 9.8 25.8 9.9 24.8 9.9 24.4 9.9 27.1 10.1 28.3 10.2 31.9 10.2 27.9 10.3 31.3 10.4 32.7 10.6 31.3 11 34.2 11.1 38.6 11.2 26.2 11.5 31.5 11.7 Volume Diameter (x) (y) 44.3 13.8 45.9 14.3 62.4 14.3 72.1 14.6 65.9 14.8 48.4 14.9 68.3 15.1 71.3 15.2 69.6 15.2 73.6 15.3 73.2 15.4 60.9 15.7 77.7 15.9 66.3 16 78.5 16.8 80.3 17.8 98.5 18.3 98.4 18.3 112.4 19.4 166.9 23.4 12.8 7.6 15.2 17.2 11.1 19 12 12.2 8 14.9 22.9 19.5 エン 32 31.8 37.1 47.1 47.7 12.2 12.5 12.9 13 8.1 8.4 8.6 8.9 9.1 9.2 9.3 9.3 19 21.2 22.7 24.7 21.3 20.9 13.1 31.6 45.1 34.5 49.1 39.4 13.1 13.4 13.8
