A. This table shows the number of traffic violations issued in the city of Arlington over the last eleven years:
Year Nr
2003 909
2004 1122
2005 938
2006 1100

On the basis of this data, project how many traffic violations will be issued in 2008 using":
1.) A three-year moving average
2.) A five-year moving average
3.) A two-year moving average where the most recent year is weighted twice as heavily as the preceding year
4.) Exponential smoothing with the starting forecast equal to 1000 for the year 2004. (Use Alpha = 0.4 and use the method without trend included)
