Question:

A graph of the luxury suite data in Question 8.2.5 suggests that the xy-relationship is linear. Moreover, it makes sense to constrain the fitted line to go through the origin, since x =0 suites will necessarily produce y = 0 revenue.
(a) Find the equation of the least squares line, y = bx.
(b) How much revenue would 120 suites be expected to generate?
