How is the smoothed value calculated for every period in a simple exponential smoothing?Group of answer choicesIt is the sum of the observation itself and the smoothed value one period ago.It is the weighted sum of the observation itself and the smoothed value one period ago.It is the average of the observation itself and the smoothed value one period ago.It is the difference between the observation itself and the smoothed value one period ago.

Consider the following time series: Period 1 2 3 4 5 6 7 8 Demand 15 24 26 33 20 22 27 20 Calculate the exponentially smoothed value for period 2 using W (smoothing coefficient) = 0.4. Express your answer without rounding.
