Following are time-series data for eight different periods. Use exponential smoothing to forecast the values for periods 3 through 8. Use the value for the first period as the forecast for the second period. Compute forecasts using two different values of alpha, α = .1 and α = .8.

Compute the errors for each forecast and compare the errors produced by using the two different exponential smoothingconstants.
