(c) The equation of the least squares regression line for the data in the scatterplot is:
score 1.62 x time + 30.8
(with r=0.94)
From this information comment on the strength and direction of the correlation, and justify
your answers
(ii)
X
(1)
Interpret the slope of this least squares regression line in terms of the variables score and
time.
