4. (12 pts) Suppose that (Y, X:) satisfy the three assumptions we made in the regression analysis, and in addition, u; is N(0,0%) and is independent of Xi. A random sample of size n = 32 is drawn and yields Y = 43.2 + 61.5 x X, R' = 0.54, SER= 1.52 (10.2) (7.4) where the numbers in parentheses are the homoskedastic-only standard errors for the regression coefficients.

0 Help Me Solve This The following data represent the yields for a five-year CD for ten banks in city A and eight banks in city B. At the 0.05 level of significance, is there evidence of a difference in the variance of the yield between money market accounts and five-year CDs?
