The ANOVA summary table to the right is for a multiple regression model with four independent variables. Complete parts (a) through (e). Determine the regression mean square (MSR) and the mean square error (MSE). MSR= 22.5 (Round to four decimal places as needed.) MSE = 17.2727 (Round to four decimal places as needed.) Compute the overall F_stat test statistic F_STat= 1.3026 (Round to four decimal places as needed.) Compute the coefficient of multiple determination, r^2, and interpret its meaning. r^2 = 0.3214 (Round to four decimal places as needed.) Interpret the meaning of the coefficient of multiple determination. The coefficient of multiple determination indicates that 32 % of the variation in the dependent variable can be explained by the variation in the independent variables
