A statistician determined that the winning times in the women's 200 m Olympic sprint can be modelled by the regression equation T= 22.249 -0.034y where Trepresents the winning time in seconds and y represents the years since 1992. a) What do the slope and y-intercept represent in this context? b) Estimate the first year when the winning time will be below 21 s. Remember that the summer Olympics occurs every four years.
