Question: (a) Refer to Commercial properties Problem 6.18. a. Obtain the analysis of variance table that decomposes the regression sum of squares into extra sums of squares associated with X4; with X1, given X4; with X2, given X1 and X4; and with X3, given X1, X2 and X4.
b. Test whether X3 can be dropped from the regression model given that X1, X2 and X4 are retained. Use the F* test statistic and level of significance .01. State the altematives, decision rule, and conclusion. What is the P-value of the test?
