Consider the ANOVA table that follows.


Analysis of Variance
Source DF SS MS F
Regression 3 3,662.36 1,220.79 27.55
Residual Error 54 2,392.82 44.31
Total 57 6,055.18

a-1. Determine the standard error of estimate. (Round your answer to 2 decimal places.)



a-2. About 95% of the residuals will be between what two values? (Round your answers to 2 decimal places.)



b-1. Determine the coefficient of multiple determination. (Round your answer to 3 decimal places.)



b-2. Determine the percentage variation for the independent variables. (Round your answer to 1 decimal place.)



c. Determine the coefficient of multiple determination, adjusted for the degrees of freedom. (Round your answer to 3 decimal places.)
