Maintaining two decimal places is required for all calculations 8) What is the forecast for week 16 using exponential smoothing with a=0.22 Assume that the forecast for week I was 55. The final forecast for period 16 should be rounded off to the nearest whole number. A) Less than or equal to 63.00 B) Greater than 63.00 but less than or equal to 66.00 C) Greater than 66.00 but less than or equal to 69.00 D) Greater than 69.00 but less than or equal to 72.00 E) Greater than 72.00 9) What is the forecast for week 16 using exponential smoothing with a = 0.6? Assume that the forecast for week I was 55. The final forecast for period 16 should be rounded off to the nearest whole number. A) Less than or equal to 63.00 Greater than 63.00 but less than or equal to 66.00 Greater than 66.00 but less than or equal to 69.00 Greater than 69.00 but less than or equal to 72.00 Greater than 72.00 10) What is the mean square error (MSE) for the forecast with a = 0.2 as of week 15? Do not use week one in your calculations. A) Less than or equal to 63.00 B) Greater than 63.00 but less than or equal to 66.00 Greater than 66.00 but less than or equal to 69.00 Greater than 69.00 but less than or equal to 72.00 Greater than 72.00 SA
