Unformatted text preview: Rearrange each function as follows: b 2 x = ˆ yb 1 and β 2 x = E ( y  x )β 1 . Note that E ( y  x 7 ) is a point on the population regression function line labelled above. (c) In this case, which is greater in absolute value: β 2 x 7 or b 2 x 7 ? (Hint: you can answer this without an answer for part (b).) (1 point) Because the slope of the sample regression function is greater than the population regression function, b 2 x 7 > β 2 x 7 . You can also see this by looking at the distances labelled on the graph above....
