Consider the following time series data: 
a. Construct a time series plot. What type of pattern exists in the data?
b. Develop a three-week moving average for this time series. Commute MSE and a fore-cast for week 8.
c. Use ? = 0.2 to compute the exponential smoothing values for the time series. Compute MSE and a forecast for week 8.
d. Compare the three-week moving average forecast with the exponential smoothing forecast using ? = 0.2. Which appears to provide the better forecast based on MSE?
e. Use Excel Solver or LINGO to find the value of ? that minimizes MSE. ( Hint : Minimize the sum of squared error.)
