I believe that if I am reading it correctly it should be greater than or equal to seven. I get confused with these though!

Maturity Annual Yield 1 year 10.0% 3 years 9.0% 6 years 7.5% 9 years 7.0% 12 years 6.5% 15 years 5.5% Using the pure expectations theory, forecast the annual interest rate on nine-year Treasuries six years from now. Select the range in which the correct answers falls. (That is what will be the annual yield on a Treasury with nine years until maturity issued six years from today?) Use arithmetic averages. Less than 4% Greater than or equal to 4%, but less than 5% Greater than or equal to 5%, but less than 6% Greater than or equal to 6%, but less than 7% O Greater than or equal to 7%
