Suppose the interest rate on a 1-year T-bond is 2.66%, that on a 2-year T-bond is 2.87%, that on a 3-year T-bond is 3.15%, and that on a 4-year T-bond is 3.36%. Assume that the pure expectations theory is valid, what is the yield on a 2-year T-bond expected to be two years from now? Round the intermediate calculations to 6 decimal places and final answer to 4 decimal places
