O Part (a)
O Part (b)
O Part (c)
O Part (d)
O Part (e)
O Part (f)
O Part (g)
Is the least squares line valid for page 200? Why or why not?
O Yes, the line produced a valid response for the maximum value.
O No, using the regression equation to predict the maximum value for page 200 is extrapolation.
O Part (h)
What is the slope of the least-squares (best-fit) line? (Round your answer to three decimal places.)
Interpret the slope.
As the page number increases by one page, the discount decreases by $
