2. How much wood Is In that tree? For a sample of 12 trees, the volume of lumber (y) (in cubic meters) and the diameter (x) (in centimeters) at a fixed height above ground level was measured. The following summary statistics were obtained: X = 36.1 x = 8.8 y= 0.86 Sy = 0.49 /= 0.94 a. Compute the least-squares regression line for predicting volume from diameter. b. If the diameters of two trees differ by 8 centimeters, by how much do you predict their volumes to differ? c. Predict the volume for a tree whose diameter is 44 centimeters
