QUESTIONS:

Using backward elimination, which of the five variables is the first eliminated? O No variable is eliminated at the first run O age O weight O height O fishmlwk O restime Indicate the p-value of the first eliminated variable, rounded off to ONLY FOUR decimal places. If no variable is eliminated at first run, write O. Using backward elimination, which of the four remaining variables is the second eliminated? O age O height O restime O fishmlwrk O No variable is eliminated at the second run O weight Indicate the p-value of the second eliminated variable. rounded off to ONLY FOUR decimal places. If no variable is eliminated at second run, write O. Using backward elimination, which of the 3 remaining variables is the third eliminated? O fishmlwk O weight O height O age O restime O No variable is eliminated at the third run Indicate the p-value of the 3rd eliminated variable, rounded off to ONLY FOUR decimal places. If no variable is eliminated at 3rd run, write 0.Using backward elimination, which is the fifth and final variable eliminated? O restime O height O fishmlwk O age O weight O No variable is eliminated at the fifth and final run Indicate the p-value of the 5th and final eliminated variable, rounded off to ONLY FOUR decimal places. If no variable is eliminated at 5th and final run, write 0.

Given the final model, indicate the residual value of the 35th sample unit, rounded off to only FOUR decimal places. Given the final model, what is the MAPE value? Given the final model, what is the RMSE value?What is the Kolmogorov-Smirnov test statistic value for the residuals of the final model, rounded off to only FOUR decimal places? What can you say about the scatterplot of the residuals and DV values from the final model? O Not funnel-shaped, indicative of non-constancy in variance O Funnel-shaped, indicative of non-constancy in variance Funnel-shaped, indicative of constancy in variance O Not funnel-shaped, indicative of constancy in variance What is the tolerance value from the final model, rounded off to only 4 decimal places? What is the largest Cook's distance value from the final model, rounded off to only four decimal places
