2. The table below shows the results of an experiment that relates the height at which a ball is dropped, x, to the height of its first bounce, y. Drop Height (x)
(cm) Bounce Height (y)
(cm)
100 26
90 23
80 21
70 18
60 16

Find , the mean of the drop heights. Find , the mean of the bounce heights. Find the linear regression equation that best fits the data. Write the equation you would use to show that is a point on the line of regression.
