Figure 4 shows a time series plot of the annual emissions of carbon dioxide (CO₂) from the consumption of coal in the USA, 1980 to 2006, in millions of tons. Figure 4 CO2 emissions 2200- 2000- 1800- 1600- 1400- 1980 1982 1984 1986 1988 1990 1992 1994 Year 1996 1998 2000 2002 2004 2006 (a) It is proposed to use Holt's exponential smoothing to forecast future values of this time series. Give 2 reasons why this is an appropriate method for this time series. (b) The first 3 values of this time series are: 1435, 1481, and 1429. Suggest starting values for the level and slope parameters.
