Answer questions 11-15 please
11. The correct formula for a k period moving average is C. d. 12. Why might a forecaster calculate MSE values on just the most recent data in the time-series data set? a. The forecaster might be interested in how well the forecasting method performs on the more recent data. b. Because the most recent data may be a better predictor of future values c. Because the resulting forecasting function might fit the older data better that the more recent dat:a. d. All of these. | 13. As the number of periods in the forecast, k, increases a. the moving average prediction will be smoother b. it is harder to get a good forecast. c. the forecast will respond more quickly to changes in the data. d·th moving average will increase in value. 14. The correct formula for the weighted moving average extrapolation technique with different weights is 15. The determination of the MSE-minimizing value of the wi is a non-linear optimization problem because a. because absolute values are used. b. the wi are fractional. c. the wi sum to 1 d. MSE is a non-linear objective function.Explanation / Answer
