(b) Use a three-week moving average to develop a forecast (in cases) for week 11. (Round your answer to two decimal places.) F11​= cases (c) Use exponential smoothing with a smoothing constant of α=0.9 to develop a forecast (in cases) for week 11 . (Round your answer to two decimal places.) F11​= cases (d) Which of the two methods do you prefer? Why? Exponential smoothing with α=0.9 is preferable since it has a smaller MSE compared to the 3-week moving average. O The 3-week moving average is preferable since it has a larger MSE compared to exponential smoothing with a=0.9. The 3-week moving average is preferable since it has a smaller MSE compared to exponential smoothing with α=0.9. Exponential smoothing with α=0.9 is preferable since it has a larger MSE compared to the 3 -week moving average. (a) Construct a time series plot. i) C i) What type of pattern exists in the data? The time series plot indicates a cyclical pattern. The time series plot indicates a trend pattern. The time series plot indicates a seasonal pattern. The time series plot indicates a horizontal pattern.
