Answer

Answer:

-0.2

Explanation:

Step1: Calculate predicted value

When $x = 3$, substitute into $y = 1.6x-4$. So $y_{predicted}=1.6\times3 - 4=4.8 - 4 = 0.8$.

Step2: Find residual value

Residual = Observed - Predicted. From the table, when $x = 3$, $y_{observed}=-1$. So residual $=-1 - 0.8=-0.2$.
