In a time series regression of the excess return of a mutual fund on a constant and the excess return on a market index, which of the following statements should be true for the fund manager to be considered to have “beaten the market” in a statistical sense? Select one: a. The estimate for Beta (parameter) should be positive and statistically significant b. The estimate for Beta (parameter) should be positive and statistically significant c. The estimate for Beta (parameter) should be positive and statistically significantly greater than the risk-free rate of return d. The estimate for Beta (parameter) should be negative and statistically significant.

Just number 3 please thankyou

You and your research partner want to use Instrumental Variable analysis to write an econometrics paper and find causal estimates. Your partner argues that because the residuals and the instrument are uncorrelated, the exogeneity requirement is satisfied. What do you tell your research partner: a) You agree, the exogeneity requirement is satisfied by construction  b) You agree, the exogeneity requirement is satisfied by their demonstration c) You disagree, you would need the results of the White Test to make this conclusion d) You disagree, the exogeneity requirement cannot be tested as we do not observe the error terms e) You cannot make any conclusions with the current information

A pension fund manager is considering three mutual funds. The first is a stock fund, the second is a long-term bond fund, and the third is a money market fund that provides a safe return of 8%.
