Question:

Determine the least-squares regression line for the data in Exercise 15.7, then calculate the sum of the squared deviations between y and ŷ.
In exercise
A scatter diagram includes the data points (x = 3, y = 8), (x = 5, y = 18), (x = 7, y = 30), and (x = 9, y = 32). Two regression lines are proposed: (1) ŷ = 5 + 3x, and (2) ŷ = – 2 + 4x.
