You can smooth a series using moving average if trend is not observed after plotting a time series data. True False

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.

asked to calculate 3 months moving average, Is it same as the forecast example:3 month moving average for April = (jan + feb + mar)/3

Which of the following statements about moving averages is not true? (a) It gives greater weight to more recent data (b) It is simpler than the method of exponential smoothing (c) It can be used to smooth a series (d) It gives equal weight to all values in the computation
