Consider the following multiple regression ModifyingAbove Price with caret equals 118.3 plus 0.575 BDR plus 24.2 Bath plus 0.166 Hsize plus 0.002 Lsize plus 0.057 Age minus 47.2 Poor comma Upper R overbar squared equals 0.71 comma SER equals 42.9 (22.4) (2.21) (7.82) (0.013) (0.00053) (0.394) (10.4) The numbers in parentheses below each estimated coefficient are the estimated standard errors. A detailed description of the variables used in the data set is available here LOADING Suppose you wanted to test the hypothesis that BDR equals zero. That is, Upper H 0 : BDR equals 0 vs Upper H 1 : BDR not equals 0 Report the t-statistic for this test. The t-statistic is nothing

Suppose you win a small lottery and have the choice of two ways to be paid: you can accept the money in a lump sum or in a series of payments over time. if you pick the lump sum, you get $2,950 today. if you pick payments over time, you get three payments: $1,000 today, $1,000 1 year from today, and $1,000 2 years from today. 1) at an interest rate of 6% per year, the winner would be better off accepting the (lump sum / payments over time), since it has the greater present value. 2) at an interest rate of 9% per year, the winner would be better off accepting the (lump sum / payments over time), since it has the greater present value. 3) years after you win the lottery, a friend in another country calls to ask your advice. by wild coincidence, she has just won another lottery with the same payout schemes. she must make a quick decision about whether to collect her money under the lump sum or the payments over time. what is the best advice to give your friend? a) the lump sum is always better. b) the payments over time are always better. c) it will depend on the interest rate; advise her to get a calculator. d) none of these answers is good advice.
