Correct. The two interpretations for the prediction have different error estimates. Since the interval estimating the mean (4,202, 4,620) is narrower than the interval estimating the volume of a particualr tree (3,517, 5,306), the error for the mean volume in board feet is less than the error for the board feet of a particular tree.
