The U.S. Federal Reserve tracks household personal savings. Personal saving is a percentage of disposable personal income (DPI), frequently referred to as "the personal saving rate," and is calculated as the ratio of personal saving to DPI. Personal saving is equal to personal income less personal outlays and personal taxes; it may generally be viewed as the portion of personal income that is used either to provide funds to capital markets or to invest in real assets such as residences.

The 10-yearTreasury noteisa debt obligation issued by the United States government with a maturity of 10 years upon initial issuance. A 10-year Treasury note pays interest at a fixed rate once every six months and pays the face value to the holder at maturity. It's also seen as a sign of investor sentiment about the economy. A rising yield indicates falling demand for Treasury bonds, which means households are more inclined to increase savings of disposable personal income. A falling yield suggests the opposite.

Does the data support the hypotheses that higher yields on 10-year U.S Treasury notes induce a higher personal savings rate?

The data in the DPI worksheet of the S&P 500 file provides data on the monthly yield on U.S. Treasury yield and personal savings rate from 1963-2021. On a separate worksheet construct a scattergram to test the hypothesis. In the assignment comment box, state your findings and conclusion.
