Answer

Explanation:

Step1: Calculate predicted y - value

Substitute (x = 12) into (y=0.45x + 8.8). [y_{predicted}=0.45\times12 + 8.8=5.4+8.8 = 14.2]

Step2: Determine actual y - value from scatter - plot

From the scatter - plot, when (x = 12), the actual (y) - value (y_{actual}=14).

Step3: Calculate the residual

Residual (=y_{actual}-y_{predicted}). [Residual = 14 - 14.2=- 0.2]

Answer:

B. -0.2
