Using interpolation, fill in the treasury yield data for every year up to Year 10. That is it, for the four-year yields, use the simple average of the yields for Years 3 and 5. For the eight-year yield, use a weighted average that uses 2/3rds of the yield in Year 7 and 1/3 of the yield in Year 10. What can you say about the relation between term to maturity and bond yields? Support your assertion with numbers from the table.
