Assume that variables x and y have a significant correltation, and that the line of best fit has been calculated as y^=1.9+1.4x. One observation is (9,15.4).
What is the predicted value of y for the value x=9?
What is the residual for the value x=9?
What is the best interpretation for the residual?
The value 9 is above the average value for y when y=15.4
The value 15.4 is below the average value for y when x=9
The value 15.4 is above the average value for y when x=9.
The value 15.4 is below the average value for x when
