(a) 2.8
(b) 3.8
(c) 8.3
(d) 2.5
ANSWER: A
For any regression model we know that evaluating the estimated equation at the means will return
the mean.
Mathematically, y = b1 + b2 x2 + b3 x3
= 9 = b1 + 1.2(3) + 1.3(2) = b1 = 2.8

ANSWER: A
Please refer to the denition and the computation of the instrumental variables (IV) estimator.
The whole point of this approach is that the IV estimator is consistent (even though the OLS
estimator might not be). In addition, it turns out to be
(c) that larger classes are associated with smaller testscores, but the eect is moderate relative
to the mean testscore
(d) that larger classes are associated with smaller testscores, but the size of the eect is hard to
interpret

We found a nega
(c) the slope no longer indicates the eect of a unit change of X on Y in the log-linear model.
(d) the regression R2 can be greater than one in the second model.
