The following model can be used to study whether campaign expenditures affect election outcomes:
voteA 5 b0 1 b1log(expendA) 1 b2log(expendB) 1 b3 prtystrA 1 u,
where voteA is the percentage of the vote received by Candidate A, expendA and expendB
are campaign expenditures by Candidates A and B, and prtystrA is a measure of party
strength for Candidate A (the percentage of the most recent presidential vote that went
to A’s party).
(i) What is the interpretation of b1?
(ii) In terms of the parameters, state the null hypothesis that a 1% increase in A’s expenditures
is offset by a 1% increase in B’s expenditures.
(iii) Estimate the given model using the data in VOTE1.RAW and report the results
in usual form. Do A’s expenditures affect the outcome? What about B’s expenditures?
Can you use these results to test the hypothesis in part (ii)?
(iv) Estimate a model that directly gives the t statistic for testing the hypothesis in part
(ii). What do you conclude? (Use a two-sided alternative.)

Suppose that jim plans to borrow money for an education at texas a& m university. jim will need to borrow $25,000 at the end of each year for the next five years (total=$125,000). jim wishes his parents could pay for his education but they can’t. at least, he qualifies for government loans with a reduced interest rate while he is in school. he has a special arrangement with aggiebank to lend him the money at a subsidized rate of 1% over five years without having to make a payment until the end of the fifth year. however, at the end of the fifth year, jim agrees to pay off the loan by borrowing from longhorn bank. longhorn bank will lend him the money he needs at an annual interest rate of 6%. jim agrees to pay back the longhorn bank with 20 annual payments and the payments will be uniform (equal annual payments including principal and interest). (i) calculate how much money jim has to borrow at the end of 5 years to pay off the loan with aggiebank. a. $121,336 b. $127,525 c. $125,000 d. $102,020 e. none of the above
