The following output was obtained using the “trees” data that comes with the MINITAB software, with the objective being to predict the volume of a tree from knowledge of its diameter and height (in feet), with the latter being easier to determine than the volume.
(a) Fill in the four blanks.
(b) When regression is used for prediction, it is generally for predicting what will happen in the future. If, however, in this application we know the diameter and height of a particular tree, are we trying to predict the future height of that tree, or another tree, or neither tree? Explain.
