The following table includes the information about a monthly time series. Month Time Series January 21 February 17 March 19 April 24 When the exponential smoothing method with α = 0.1 and α = 0.5 is applied, what is the speed of decline for which the mean absolute deviation is better? What is this mean? Multiple Choice A. α = 0.1 and MAD = 3.05. B.α = 0.1 and MAD = 3.00. C. α = 0.5 and MAD = 3.00. D. α = 0.5 and MAD = 3.05.
