Develop two exponential smoothing forecasts: one with alpha $=0\mathrm{.}2$ and another with alpha $=0\mathrm{.}7$ for periods $2-13.$ Assume your forecast for period $1$ was $220.$ Calculate the MFE, MAD, and MAPE values using data and forecasts for periods $2-12$ for both forecasting models. Which model has lower MFE, MAD, and MAPE values? Why?
