A student used multiple regression analysis to study how family spending (y) is influenced by income (x_1), family size (x_2), and additions to savings (x_3). The variables y, Xi, and xo are measured in thousands of dollars. The following results were obtained. Coefficient of determination = 0.946 Write out the estimated regression equation for the relationship between the variables. What can you say about die strength of this relationships? Carry out a test of whether y is significantly related to die independent variables. Use a .05 level of significance. Carry out a test to see if x_3 and y are significantly related. Use a .05 level of significance. Why would a coefficient of determination very close to 1.0 be expected here?
