Problem 4: a) Fill in the following ANOVA table for the model Y = B. + B,X, +B2X2 + B,X, +E. = SS df 3 MS 6.184 F 5.845 P-value 0.0017 18.553 1 14.791 Source Regression (x, X X2|X, X3|X1,X2 Error Total 1 3.761 1 1 0.001 1.058 49 52 51.854 70.407 b) Determine the following multiple partial coefficient of determination: R2(X2,X3 / X1) = c) Interpret the answer to part b). d) Determine the following multiple partial correlation coefficient e) Interpret the answer to part d). Y regressed on X1: Y regressed on X1 and X2: Y regressed on X1, X2, X3: Regression Eq: y = 5.11 -0.0476 X1 Regression Eq: y = 5.38 - 0.048 X1 + 0.023 X2 Reg. Eq: y = 5.36 -0.048 X1 + 0.018 X2 + 0.00004 X3 , f) Based upon the information provided, can you assess whether X1 is a confounder of the X2-Y relationship? Explain
