The following table gives the sales of CD_Rom drives and compact disk players for selected years and can be found in Glassman. Sales are in millions. Year 1988 1990 1992 1993 Sales 0.075 0.24 1.5 4.8 A. On the basis of this data, find the best-fitting exponential regression. Let x = 0 correspond to 1988. State the square of the correlation coefficient. (Use 4 decimal places in you answers.) S(x) = r2 = B. Use this model the estimate the sales in 1997. (Round to the nearest player.) In 1997, there were about million CD_ROM and compact disk players sold.
