A Caribbean cruise line booked the number of passengers (in thousands) described below for each quar- ter from 2005 through 2009.

	I	II	III	IV
2005	27	23	21	24
2006	32	26	18	29
2007	28	25	16	30
2008	37	31	21	34
2009	38	33	23	39

a. Combining the quarterly bookings for each year, fit a linear trend equation and forecast the number of bookings for 2013.

b. Determine the seasonal indexes and break the 2013 forecast in part (a) into its quarterly components.

c. Combining the quarterly bookings for each year, use exponential smoothing, with a 5 0.3, to forecast the number of bookings for 2010.

d. Use the seasonal indexes to break the 2010 forecast in part (c) into its quarterly components.
