% Problem 10 Question Help A convenience store recently started to carry a new brand of soft drink Management is interested in estimating future sales volume to determine whether it should continue to carry the new brand or replace it with another brand. The following table provides the number of cans sold per week. Use both the trend projection with regression and the exponential smoothing (leta=0.4 with an initial forecast for week 1 of 583) methods to forecast demand for week 13. Compare these methods by using the mean absolute deviation and mean absoluto percent error performance criteria. Does your analysis suggest that sales are trending and if so, by how much? Period 1 2 3 4 5 6 7 8 9 10 11 12 Sales 583 635 645 737 676 616 732 693 774 741 674 746 Obtain the trend projection with regression forecast The forecast for week 13 is 737. (Enter your response rounded to the nearest whole number.) Specify the mean absolute deviation (MAD) and mean absolute percent error (MAPE) (Enter your responses rounded to two decimal places.) MAD MAPE 31.91 4.76% (1) Obtain the exponential smoothing forecast The forecast for week 13 is 709. (Enter your response rounded to the nearest whole number) Specify the mean absolute deviation (MAD) and mean absoluto percent error (MAPE) (Enter your responses rounded to two decimal places.) MAD MAPE 45.99 6.64% Based on MAD, the best method is trend projection with regression Based on MAPE, the best method is trend projection with regression
