The Easy fit tire store had demand for tires shown below. Assume F1 = 198. a. Develop a spreadsheet using the first seven days of demand to determine the best exponential smoothing model for values of α = .2, α = .3, and α = .4. Select the model with the smallest absolute deviation for seven periods. b. Develop another spreadsheet using the second seven days to compare the best exponential smoothing model found in part a with a three-period moving average model. Compare the predictions on the basis of the total absolute deviation. c. What principles does this problem illustrate?
