THE NEXT QUESTIONS ARE BASED ON THE FOLLOWING INFORMATION:
Given a simple regression analysis,suppose that we have obtained the fitted regression model:
i = 6 + 8x i and also the following statistics: s e = 3.20,
= 8,n = 42,and
-A scatter diagram includes the data points (x = 2,y = 5),(x = 4,y = 12),(x = 6,y = 20),(x = 8,y = 28),and (x = 10,y = 30).Two regression lines are proposed: (1)
= -0.6 + 3x,and (2)
= -1 + 5x.Using the least squares criterion,which of these regression lines is the better fit to the data? Why?
