Answer:
10.41%
Explanation:
Calculation for the expected interest rate on a four-year maturity
Expected interest rate=[(1+.0947)^10 ÷1+.0885)^6 ]^1=4-1
Expected interest rate=[(1.0947)^10÷(1.0885)^6 ]^1/4-1
Expected interest rate=[(2.47÷1.66)^1/4]-1
Expected interest rate=(1.486^1/4)-1
Expected interest rate=1.1041-1
Expected interest rate=0.1041*100%
Expected interest rate=10.41%
Therefore the expected interest rate on a four-year maturity AA zero coupon bond purchased six years from today will be 10.41%
