Answer the fоllоwing questiоns in the text box below showing cаlculаtions аnd/or brief justification. [6 points] Calculate the three missing values in this Anova table for the multiple linear regression model, E(Y) = β0 + β1X1 + β2X2 + β3X3 + β4X4 + β5X5. Source of variation DF SS Regression ? 160.14 Residual error ? ? Total 45 187.89 Regression DF = Residual error DF = Residual error SS = [8 points] Sequential sums of squares for the model in part (a) were as follows: Source of variation DF SS X1 1 4.63 X2 1 118.89 X3 1 35.42 X4 1 1.00 X5 1 0.20 Use information in this table and the table in part (a) to perform a hypothesis test at significance level 0.05 to determine whether predictors X4 and X5 are significantly linearly related to Y upon controlling for the remaining predictors X1-X3 using a partial F-test. Write the null and alternative hypotheses, the value of the test statistic, the decision rule, and the conclusion. [Use the fact that the 95th percentile of an F-distribution with 2 numerator DF and 40 denominator DF is 3.23.] [6 points] Later it was decided to consider a regression of Y on the first 3 predictors only. Use information from both tables to calculate adjusted R2 for the model with only the first 3 predictors. [2 points] Given only the information in both tables, is it possible to test whether X1 can be dropped from the 3-predictor model? Give a brief argument supporting your answer. [You do not have to do a test, even if one is possible.]
