3. A sample of 15 of the fish was weighed. The weight, M was plotted against length, L as shown below. y 1.4 1.2 1 0.8 W (kg) 0.6 0.4 0.2 0 0 20 40 60 80 100 120 L (cm) Exactly two of the following statements about the plot could be correct. Identify the two correct statements. Note: You do not need to enter data in a GDC or to calculate r exactly. (a) The value of r, the correlation coefficient, is approximately 0.871. (b) There is an exact linear relation between W and L. (c) The line of regression of W on L has equation W = 0.012L + 0.008. (d) There is negative correlation between the length and weight. (e) The value of r, the correlation coefficient, is approximately 0.998. (f) The line of regression of W on L has equation W = 63.5L + 16.5
