Interpretation: Suggest according to naïve
Concept Introduction:Most of the forecasting methods are based on the past performances of another organization in the similar industry. The process involved in the predicting of future occurrences is call forecasting.
B
Interpretation: Calculate the expected student appointment for this week using the 3 week moving average and also the 2 week moving average.
Concept Introduction: Most of the forecasting methods are based on the past performances of another organization in the similar industry. The process involved in the predicting of future occurrences is call forecasting.
C
Interpretation: Determine the forecast for this week based on exponential smoothing method, supposing an alpha of 0.2, and a forecast 2 weeks ago was 90.
Concept Introduction: Most of the forecasting methods are based on the past performances of another organization in the similar industry. The process involved in the predicting of future occurrences is call forecasting.
D
Interpretation:Suggest the week’s forecast of student appointments based on the linear regression formula created using 4 weeks of data.
Concept Introduction:From the point where the correlation has limitations, the regression method is developed for measuring casual relationships.

- Under what conditions might a firm use multiple forecasting methods?arrow_forwardScenario 3 Ben Gibson, the purchasing manager at Coastal Products, was reviewing purchasing expenditures for packaging materials with Jeff Joyner. Ben was particularly disturbed about the amount spent on corrugated boxes purchased from Southeastern Corrugated. Ben said, I dont like the salesman from that company. He comes around here acting like he owns the place. He loves to tell us about his fancy car, house, and vacations. It seems to me he must be making too much money off of us! Jeff responded that he heard Southeastern Corrugated was going to ask for a price increase to cover the rising costs of raw material paper stock. Jeff further stated that Southeastern would probably ask for more than what was justified simply from rising paper stock costs. After the meeting, Ben decided he had heard enough. After all, he prided himself on being a results-oriented manager. There was no way he was going to allow that salesman to keep taking advantage of Coastal Products. Ben called Jeff and told him it was time to rebid the corrugated contract before Southeastern came in with a price increase request. Who did Jeff know that might be interested in the business? Jeff replied he had several companies in mind to include in the bidding process. These companies would surely come in at a lower price, partly because they used lower-grade boxes that would probably work well enough in Coastal Products process. Jeff also explained that these suppliers were not serious contenders for the business. Their purpose was to create competition with the bids. Ben told Jeff to make sure that Southeastern was well aware that these new suppliers were bidding on the contract. He also said to make sure the suppliers knew that price was going to be the determining factor in this quote, because he considered corrugated boxes to be a standard industry item. Is Ben Gibson acting legally? Is he acting ethically? Why or why not?arrow_forwardScenario 3 Ben Gibson, the purchasing manager at Coastal Products, was reviewing purchasing expenditures for packaging materials with Jeff Joyner.

Using exponential smoothing with a smoothing constant (α) of 0.30 and a starting forecast of 420.00, the following sales forecast has been developed: Year Sales Forecasted Sales 1 460 420.00 2 510 432.00 3 520 455.40 Using smoothing constants of 0.60 and 0.90, develop forecasts for the sales of VW Beetles. Use MAD to determine which of the three smoothing constants (0.30, 0.60, or 0.90) gives the most accurate forecast. The MAD for a forecast developed using exponential smoothing with α=0.30 is nothing sales. (Round your response to two decimal places.)arrow_forward
