Matt-
Brodi's interpretation is correctly. Testing the hypothesis b1=b2 is
different than testing the hypothesis b1=b2=0. (You could imagine b1 and
b2 coefficients that are both significantly different than zero but not
significantly different than one another.)

Matt,
I assumed that, like 6(d), we were meant to test whether Black and Hisp
were simultaneously equal to zero;
And as to the second half of the question, I read it as asking for a
substantive interpretation / comparison of the results, and the merits,
of the methods used in (b)-(d). (as neither (b) or (c) ask for
substantive interpretation).

Subject: [gov1000-list] 7d please
a question -
are we testing whether Black and Hisp are simultaneously equal to zero,
or
whether each one might be equal to zero? does the second half of 7d
refer
to the two tests made in question 7 all together (7b/c and one from 7d)
or
the two tests from 7d (assuming the second interpretation of my first
question?). Clearly the answer to my second question relies on the
answer
to my first.
Confusingly, and syntactically quite shockingly poor as to the way this
was written,
matt
