Final answer:
The expected yield calculations for U.S. Treasury notes require detailed information which is not fully provided. An explanation of the yield curve indicates that its shape reflects economic expectations and conditions, with variations such as an upward slope, inverted shape, or flat line suggesting growth, downturn, or uncertainty, respectively.
Step-by-step explanation:
The question deals with the calculation of the expected yields on U.S. Treasury notes given certain data and the analysis of the yield curve to infer economic implications. To answer the parts of the question regarding expected yields, one would typically use the given yields and adjust for the constant premiums provided. However, as the question seems incomplete and lacks certain details, a precise calculation is not possible. Nevertheless, one can describe that the yield curve, which graphs interest rates of bonds having equal credit quality but differing maturity dates, generally indicates market expectations for future interest rates and the health of the economy.
A normal upward-sloping yield curve indicates expectations of a growing economy, while an inverted or downward-sloping curve suggests expectations of a future economic downturn. Lastly, a flat or humped curve can indicate uncertainty about economic conditions. Specific calculations for expected yields of the notes are not completed due to incomplete information.
