the MAD Part please

Problem 15 Your answer is partially correct. Try again. Burger Lover Restaurant forecasts weekly sales of cheeseburgers. Cheeseburger Sales Week 1 3 4 5 354 345 362 321 360 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 33B cheeseburgers for the fifth week. Round your answers to 2 decimal places, the tolerance is +/-0.01. Simple average: F8 - T 348.4 3-Period moving average: F6 = 347.66 Exponential smoothing: Fg = 342.4 If actual sales for week 6 turn out to be 372, compare the three forecasts using MAD. Which method performed best? (Calculate your answers using the error only in period 6.) MAD (simple average) - 18.6 MAD (3-period moving average) = 24.67 MAD (exponential smoothing) - 22 Simple average provides the lowest MAD
