You know that you can use exponential smoothing to create forecasts when the time series exhibits gradual (not a sharp) trend, has no cyclical effects, and has no seasonal effects, and when you are forecasting only one period beyond the existing data. You are given the data set on the cigarette consumption from 1965 to 2004. Answer the following questions. 1. From the scatter plot you can conclude that: 2. o the series exhibits gradual (not a sharp) trend o the seriest exhibits a sharp change in trend o the series appears to have a cyclical component o the series does not appear to have a cyclical component o the series appears to have seasonal component o the series does not appear to have seasonal component o time series forecasting with exponential smoothing is appropriate o time series forecasting with exponential smoothing is not appropriate 3. Using the smoothing constant of 0.8, the forecasted value for the cigarette consumption in 2005 is 2700.4 Item 1: You made all of the correct selections. Item 2: Your answer is within ±1% of the solution - correct. You received a raw score of 100% on this question.
