Final answer:
The residual for AP statistics, which represents the difference between the actual and predicted percentage of students scoring a 5, is -2%.
Step-by-step explanation:
The residual for AP statistics is found by comparing the actual percentage of students who scored a 5 on the AP statistics exam to the percentage predicted by a regression line. In this case, the actual percentage is 14% and the regression line predicted that 16% of students would score a 5.
To calculate the residual, we subtract the actual percentage (14%) from the predicted percentage (16%).
Residual = Actual percentage - Predicted percentage = 14% - 16% = -2%.
Therefore, the residual for AP statistics is -2%, which indicates that the regression line overestimated the number of students who would score a 5 by 2 percentage points.
