ANSWER: The answer is residual = -0.5 yards. This means that the prediction was 0.5 yards higher than the actual value.
EXPLANATION:
To calculate the residual, we can use the formula:
residual = actual - predicted
We are given that the actual value is 11.5 yards and the predicted value is 12 yards. Therefore, we can plug these values into the formula and solve for the residual:
residual = 11.5 - 12 residual = -0.5
