Problem 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 100-meter freestyle data given in the table, where x is years since 1990 and y is winning time (in seconds). Do the same for the women’s 100-meter freestyle data. (Round regression coefficients to three decimal places.) Do these models indicate that the women will eventually catch up with the men?
