Exam Content Question 1 10 Points Which one is a false statement? A The larger the MAD, the better the forecast model. BCFE being O indicates the model is not biased C Exponential smoothing is a special case of a weighted moving average. D In simple linear regression, there is only one independent variable. Question 2 10 Points Given below are the actual demand and the forecasts made in 2018. Actual Forecast Year 2019 1st Quarter 1200 1100 2nd Quarter 900 1100 3rd Quarter 1100 1100 4th Quarter 1000 1100 What is Tracking Signal (TS) for the forecasts for the 1st, 2nd, 3rd and 4th Quarters of Year 2019? A) -0.5. B) -2.0. 4.0. Do. A large positive value for the CFE suggests: A The forecast is too high. B The forecast is not biased. The model is functioning correctly. D The forecast is too low. Question 4 10 Points Given below are the actual demand and the forecasts made in 2018. Actual Forecast Year 2019 1st Quarter 1200 1100 2nd Quarter 900 1100 3rd Quarter 1100 1100 4th Quarter 1000 1100 If you were to use a three-period weighted moving average with weights of 0.5, 0.3 and 0.2 to make a forecast for the 1st Quarter of Year 2020, what would it have been? A 1,060. B 1,090. 1,010. D 1,000. Given below are the actual demand and the forecasts made in 2018. Actual Forecast Year 2019 1st Quarter 1200 1100 2nd Quarter 900 1100 3rd Quarter 1100 1100 4th Quarter 1000 1100 What is MAD for the forecasts for the 1st, 2nd, 3rd and 4th Quarters of Year 2019? A 50. B 400. C 10. D 100. Question 6 10 Points Given below are the actual demand and the forecasts made in 2018. Actual Forecast Year 2019 1st Quarter 1200 1100 2nd Quarter 900 1100 3rd Quarter 100 1100 4th Quarter 1000 1100 If you were to use a three-period simple moving average to make a forecast for the 1st Quarter of Year 2020, what would it have been? A 1,067. B) 1,000. C 1,050. 900. Question 7 10 Points Which one is a true statement? A The larger the tracking signal, the better the model. B Tracking signal being close to O means the model is not biased. CCFE being a large negative number means the model has been under-forecasting. D Tracking signal being o means the model is 100% accurate. Question 8 10 Points Using simple moving average, if we want the forecast to be very responsive to recent demand, the number of periods (n) used should be: A large. B) zero. C moderate. D small. Question 9 10 Points Given below are the actual demand and the forecasts made in 2018. Actual Forecast Year 2019 1st Quarter 1200 1100 2nd Quarter 900 1100 3rd Quarter 1100 1100 4th Quarter 1000 1100 What is Cumulative Forecast Error (CFE) for the forecasts for the 1st, 2nd, 3rd and 4th Quarters of Year 2019?
