Consider the following time series data: Month 1 2 3 4 5 6 On 7 Value 24 15 21 12 19 21 16 (a) Choose the correct time series plot. (1) 30 25 20 Value 15 10 5 0 1 5 Month (HD) 30 25 20 Value 15 10 Month Graph (1) What type of pattern exists in the data? - Select your answer - (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: The forecast for month B (c) Ute 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 The forecast for month 8: (a) Compare the three-month moving average forecast with the exponentiat smoothing forecast using a = 6.2. Which appears to provide the better forecast based on MSE? Select your answer (e) Use trial and error to find a value of the exponential smoothing coefficient a that results in the smallest MSE Do not round intermediate calculations. Use a two decimal digit precision for the exponential smoothing coefficient
