a) Interpret the model from a financial perspective. That is, what are these four estimated coefficients telling you about Apple’s systematic stock market performance? Does each make theoretical and intuitive sense? Explain your answers. (Note that a non-zero intercept (alpha (a)) denotes the presence of arbitrage opportunities.)

b) Comment briefly on the statistical significance of the intercept and each of the independent variables as indicated by their t-ratios and on the statistical significance of the model as a whole as indicated by the F-ratio. What is the interpretation of R

^{2}?

c) The graph below shows the residual plot for the estimated three factor equation. Considering both auto- or serial correlation and heteroskedasticity, what, if any, potential problems do you see?
