*Problem 15 Your answer is partially correct. Try again. Burger Lover Restaurant forecasts weekly sales of cheeseburgers. Week Cheeseburger Sales 353 343 363 321 356 Based on historical observations over the past five weeks, make a forecast for the next period using the following methods: simple average, three-period moving average, and exponential smoothing with a = 0.2, given a forecast of 339 cheeseburgers for the fifth week. Round your answers to 2 decimal places, the tolerance is +/-0.01. Simple average: F6 = 348.8 3-Period moving average: F6 = 348.33 Exponential smoothing: F6 = 336.40 If actual sales for week 6 turn out to be 366, compare the three forecasts using MAD. Which method performed best? (Calculate your answers using the error only in period 6.) MAD (simple average) = 119.2 MAD (3-period moving average) = 1119.67 MAD (exponential smoothing) = 131.60 Simple average provides the lowest MAD
