a. Choose the correct graph for the monthly data. The correct graph is b. Compute the sales forecast for July using the approaches given below. Do not round intermediate calculations. Round your answers to the nearest whole number. 1. a three-month moving average computers 2. a weighted three-month moving average using 0.40 for June, 0.40 for May, and 0.20 for April computers 3. a linear trend equation computers 4. exponential smoothing with a (smoothing constant) equal to 0.40 , assuming a February forecast of 18,000 computers c. Calculate the MAD for each of the four techniques in part b. Use only the last 3 months to compare the same number of months for all methods. Do not round intermediate calculations. Round your answers to the nearest whole number. MAD (three-month moving average): computers MAD (weighted three-month moving average): computers MAD (linear trend equation): computers MAD (exponential smoothing): computers Which is the best? Why? is better because it provides the MAD. a. Choose the correct graph for the monthly data. The correct graph is b. Compute the sales forecast for July using the approaches given below.
