a.   What are the forecasts for days 4 through 8 using a 3-period moving average model?  Round the forecasts to two decimal places.

b.  With an alpha value of .4 and a starting forecast in day 3 equal to the actual data, what are the exponentially smoothed forecasts for days 4  through 8?  Round the forecasts to two decimal places.

c.   What is the MAD for the 3-period moving average forecasts for days 4 through 7?  Compare it to the MAD for the exponential smoothing forecasts for days 4 through 7.
