Problems require a graphing calculator or a computer that can calculate the linear regression line for a given data set.

Olympic Games. Find a linear regression model for the men's 200-meter backstroke data given in Table 16, where x is years since 1980 and y is winning time (in seconds). Do the same for the women's 200-meter backstroke data. (Round regression coefficients to four decimal places.) Do these models indicate that the women will eventually catch up with the men?
