3. Assessing the forecasting ability of the yield curve

a. What was the difference between the 26-week T-bill yield and the 13-week T-bill yield at in September 2023?

b. Does this imply that the yield curve had an upward or downward slope at that time?

c. Assuming that this slope can be primarily attributed to expectations theory; did the direction of the slope indicate that the market expected higher or lower interest rates in the future?

d. Did interest rates move in that direction over the course from September 2023 to November 2023?
