Consider the following time series data. (a) Choose the correct time series plot. Time Series Value Time Seres Value s^ Time Seres Value (b) Develop a three-week moving average for this time series. Compute MSE and a forecast for week 7. Do not round intermediate calculations. If required, round your answers to two decimal places. (b) Develop a three-week moving average for this ume series. Compute MSt and a forbcathor weGk? Do not round intermediate calcuations. If required, round yout answers to two decimal places. MSE: The forecast for week 7 (c) Use a=0.2 to compute the exponential smoothing values for the time series. Compute MSE and a forecast for week 7 . Do not round intermediate calculations. If required, round your answers to two decimal places. (c) Use a = a 2 to compute the exponential smoothing values for the ume series. Compote MSf and a forecmt for wekk.7 Da not raund interrnedate calculatisns if required, round your answers to two decirlal pisces (d) Compare the three-week moving average forecast with the exponential smoothing forecast using a = 0.2 . Which appears to provide the better fored based on MSE? Explain. Using this approwch resuits in a MSE e) Use trial and error to find a value of the exponential smoothing coefficient a that yields the minimum MSE. Do not round intermediate calculation two-decimal digit precision for the exponential smoothing coefficient: alpha: Hide Feedback
