The point (9.1,71) is a point on the
(I = 3,y = 191). Indicate the residual for z = 9.1 by drawing the vertical line between
(9.1, 71) and the corresponding point on the regression line. Will the residual be a positive or negative value?
(f) Find the value of the residual for x = 9.1.
Expert Solution
Step 1
Given information:
The point (9.1, 71) is a point on the scatterplot.
Another point is (I = 3,y = 191).
Let (x1, y1)=(9.1, 71) and (x2, y2)=(3, 191)
Let us consider the regression line as
