Exponentially Smoothed Series (a = 0.8) Ratio 1.48 The table below shows the inventory-sales ratio for manufacturing and trade for a region over a period of 8 years. Use the method of simple exponential smoothing to obtain forecasts of the inventory-sales ratio over the next 4 years. Use a smoothing constant of a = 0.8. Graph the observed time series and forecasts. Year 1 Complete the table below.
