In the following regression (see attached data), X=total assets (\$ billions), Y=total revenue (\$ billions), and n=64 large banks.

a. Write the fitted regression equation.

b. State the degrees of freedom for a two-tailed test for zero slope, and use Appendix D (see attached data) to find the critical value at a=.05.

d. Interpret the 95 percent confidence limits for the the slope.

e. Verify that F=t^2 for the slope.

f. Describe the fit of this regression.
