Answer:

-4.5

Step-by-step explanation:

The predicted value from the model is calculated by substituting x with 4 in the regression equation;

y = 5(4) - 2.5

y = 17.5

The actual value when x is 4 is given as 13. The residual is simply the difference between the actual and the predicted value;

residual = actual value - predicted value

residual = 13 - 17.5

residual = -4.5
