Suppose that the interest rate on a one$-$year Treasury bill is currently $7\%$ and that investors expect that the interest rates

on one$-$year Treasury bills over the next three years will be $8\%,9\%,$ and $7\%.$ Use the expectations theory to calculate

the current interest rates on two$-$year, three$-$year, and four$-$year Treasury notes.

The current interest rate on two$-$year Treasury notes is $\%.($Round your response to two decimal places.$)$
