Does the residual plot show that the line of best fit is
Iteru [2.4K]

Answer:

e_1 = 3.5-4.06= -0.56

e_2 = 2.3-2.09= 0.21

e_3 = 1.1-0.12= 0.98

e_4 = -2.2-(-1.85)= -0.35

e_5 = -4.1-(-3.82)= -0.28

The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:

Yes, the points are in a curved pattern.

Step-by-step explanation:

The correct formula for the residuals is given by:

e_i =y_i -\hat y_i

Who represent the observed value minus the predicted. We can find the individual residuals and we got:

e_1 = 3.5-4.06= -0.56

e_2 = 2.3-2.09= 0.21

e_3 = 1.1-0.12= 0.98

e_4 = -2.2-(-1.85)= -0.35

e_5 = -4.1-(-3.82)= -0.28

The plot is on the figure attached. And we can see that the residuals shows a curved pattern so then the best conclusion for this case would be:

Yes, the points are in a curved pattern.
