What type of pattern exists in the data? 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 8 : Use \( \alpha=0.2 \) to compute the exponential smoothing values for the 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 8 : Compare the three-month moving average forecast with the exponential smoothing forecast using \( \alpha=0.2 \). Which appears to provide the better forecast based on MSE? Use trial and error to find a value of the exponential smoothing coefficient \( \alpha \) that results in the smallest MSE. If required, round your answer to two decimal places. \( \alpha= \) Consider the following time series data: (a) Choose the correct time series plot.
