In the following regression, 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 to find the critical value at α = .05.
(c) What is your conclusion about the slope?
(d) Interpret the 95 percent confidence limits for the slope.
(e) Verify that F = t2 for the slope.
(f) In your own words, describe the fit of this regression.
