Develop the best multiple regression model using this information and identify the appropriate adjusted R square value for the fit period below. (Points : 4) 99.5% 87.5% 79.3% 98.8% 67.4%Question 24. 24.Does the best regression model have significant multicollinearity? (Points : 4) No since the D-W statistics is below 2.5. No since the VIFs are below 2.5 Yes since the F value is very high at 745.9. No since the constant term is significant.Question 25. 25.Does the best regression model that you ran in problem 23 have severe serial correlation? How can you tell? (Points : 4) No since the D-W statistic is between the lower limit and 4 minus the lower DW table limit. Yes, since the D-W statistic is lower than the lower DW table limit. Yes, since the VIF is less than 2.5. No, since the F value and R square value are large.Question 26. 26.Given the forecast values for each of the X variables and the fact that you are not expecting a worker’s strike over the forecast period what is your forecast of sales revenues for August of 2011? (Points : 4) 148.1 146.6 138.2 158.1 163.6Question 27. 27.What is the fit period MAPE for your best regression model (Points : 4) 5.8 Percent 1.1 Percent 4.1 Percent 6.4 Percent 13.1 PercentQuestion 28.28.What is a major indication that management has lost control over the operation of a company? (Points : 3) Infrequent executive level meetings. The lack of quantitative forecasting used for major business drivers. Mistrust in the basic business driver forecast and forecast effort duplication.
