We are studying mutual bond funds for the purpose of investing in several funds. For this particular study, we want to focus on the assets of a fund and its 5-year performance. The question is: Can the 5-year rate of return be estimated based on the assets of the fund? Nine mutual funds were selected at random, and their assets and rates of return are as follows:


Fund Assets ($ millions) Return (%) Fund Assets ($ millions) Return (%)
AARP High Quality Bond $ 622.2 10.8 MFS Bond A $ 494.5 11.6
Babson Bond L 160.4 11.3 Nichols Income 158.3 9.5
Compass Capital Fixed Income 275.7 11.4 T. Rowe Price Short-term 681.0 8.2
Galaxy Bond Retail 433.2 9.1 Thompson Income B 241.3 6.8
b-2. Compute the coefficient of determination.
d. Determine the regression equation. Use assets as the independent variable. (Round your answers to 4 decimal places. Negative amounts should be indicated by a minus sign.)
