Using the website www.research.stlouisfed.org/fred2/, retrieve interest rate data at the beginning of the last 20 quarters for the federal funds rate and the threemonth Treasury bill (T-bill) rate, and place the data in two columns of an Excel spreadsheet. Derive the change in interest rates on a quarterly basis. Apply regression analysis in which the quarterly change in the T-bill rate is the dependent variable (see Appendix B for more information about using regression analysis). If the Fed’s effect on the federal funds rate influences other interest rates (such as the T-bill rate), there should be a positive and significant relationship between the interest rates. Is there a positive relationship? Explain.
