Use explanation correctly
![Use a graphing calculator to find a linear regression model for the men's 100-meter freestyle data given in the table on
the right where xis years since 1980 and y is winning time (in seconds). Do the same for the women's 100-meter
freestyle data. Do these models indicate that the women will eventually catch up with the men?
The men's linear regression model is
y = 50.107-0093x
(Round regression coefficients to three decimal places as needed.)
The women's linear regression model is
Y-O
(Round regression coefficients to three decimal places as needed.)
