The analyst in Exercise fits the model with the four predictor variables. The regression output shows:
Response Variable: Spending
R2 = 84.92% Adjusted R2 = 84.85%
s = 48.45 with 908 - 5 = 903 degrees of freedom

a) How many observations were used in the regression?
b) What might you do next?
c) Is it clear that Income is more important to predicting Spending than Networth? Explain.
