please try to do all parts! if you cannot, I need help for subsets part E , F , & G

thank u:)

Consider the total production (and sales) of ice cream in Canada (in millions of liters) for a period of 13 years until 2019 (from left to right) 341, 331, 317, 315, 321, 278, 298, 311, 302, 302, 335, 320, 285 Fit a model to ice cream production data using each of the following techniques and forecast the 2020 production in each case. a) Two-year moving average. (3 point) b) Four-year moving average. (3 point) c) Exponential smoothing with smoothing constant = 0.2. (5 point) d) Exponential smoothing with smoothing constant = 0.4. (5 point) e) Linear trend projection (linear regression). (9 point) f) Plot a graph and determine which of the above techniques would you use to forecast the ice cream production and why? (Hint: The plot overall closest to actual demand will be most accurate). (5 point) g) Alternatively, compute the MAD for each forecasting technique and determine the most accurate technique. (5 point)
