Final answer:
The bond's effective annual yield can be calculated using the formula (1 + Semi-Annual Yield)^2 - 1. Plugging in the values, we get an effective annual yield of 12.36%.
Step-by-step explanation:
The effective annual yield of a bond can be calculated using the formula:
Effective Annual Yield = (1 + Semi-Annual Yield)^2 - 1
Given that the bond in question has a semi-annual coupon rate of 8%, we can calculate the semi-annual yield using the formula:
Semi-Annual Yield = Coupon Payment / Bond Price
Plugging in the values, we get:
Semi-Annual Yield = 80 / 1166.62 = 0.0685
Using the formula for the effective annual yield, we can calculate:
Effective Annual Yield = (1 + 0.0685)^2 - 1 = 0.1236 = 12.36%
Therefore, the bond's effective annual yield is 12.36%, which corresponds to option (a).
