Find the least-squares regression line y = bo + b₁x through the points
(-2,0), (0,7), (4, 15), (8, 18), (9,24),
and then use it to find point estimates y corresponding to x = 1 and x = 8.
For this problem and to give you practice for the test, use the shortcut method to find bo given that b₁ = 1.9051724137931.
For x = 1, y =
For x = 8, y^=
