A study considered the Olympic medal winners (gold, silver and bronze)
time in the mens 100 metre dash from 1900 till 2008. A plot of calendar
year versus official time (measured in seconds) recorded to complete the race
showed a definite linear relationship between the variables. The equation of
the linear regression line was found to be
Time = 33.78 0.01194Year.
(a) For the regression line, identify what the slope is and interpret its mean-
ing in the context given here.
So Is the slope 33.78 because y= mx + b and mx is the slope value? Is my answer right?
