A) What is the value of the multiple correlation (that is, the correlation between the dependent variable and the set of independent variables)?
B) What proportion of the variability in number of children is explained by the three independent variables?
C) Of the three independent variables, which has the weakest net effect on the dependent variable?
D) Write out the regression equation. (You may use Y and Xs in the regression equation or, in place of the Y and Xs, you may use variable names. Don't forget the subscripts on the Xs if you use Y and Xs.)
