Compute the Macaulay duration under the following conditions:

1. A bond with a four-year term to maturity, a 10% coupon (annual payments), and a market yield of 9%. Do not round intermediate calculations. Round your answer to two decimal places. You may use Appendix C to answer the questions. Assume $1,000 par value.
