need answer for part (e)

Consider the following time series data: 6 Month Value 1 2 24 13 3 20 4 5 12 1923 shment Graph (1) What type of pattern exists in the data? Horizontal pattern (b) Develop a three-month moving average for this time series. Compute MSE and a forecast for month 8. If required, round your answers to two decimal places. Do not round intermediate calculation MSE: 27.5 The forecast for month 8: 19 (c) Use a 0.2 to compute the exponential smoothing values for the time series. Compute MSE and a forecast for month & If required, round your answers to two decimal places. Do not round intermediate calculation. MSE: 42.14 The forecast for month 8: 19.12 (d) Compare the three-month moving average forecast with the exponential smoothing forecast using a = 0.2. Which appears to provide the better forecast based on MSE? 3-month moving average : (e) Use trial and error to find a value of the exponential smoothing coefficient o that results in the smallest MSE If required, round your answer to two decimal places. = Hide Feedback 3 Partially Correct
