Use the simple exponential smoothing technique with a = 0.2 to make a forecast for Week 53. (Do not round intermediate calculations. Round final answer to 2 decimal places.) 953 = 1,325.99 b. Use the simple exponential smoothing technique with a = 0.4 to make a forecast for Week 53. (Do not round intermediate calculations. Round final answer to 2 decimal places.) 553 = 1,401.02 c-1. Which is the preferred technique for making the forecast based on MSE, MAD, and MAPE? (Do not round intermediate calculations. Round final answers to 2 decimal places.) MSE MAD Technique a = 0.2 a = 0.4 11,501.64 90.52 70.79 MAPE (%) 8.15 6.49 7,183.08 c-2. Which is the preferred technique for making the forecast? a = 0.2 because it has the largest 3 out of 3 performance measures
