Question
The scatterplot shows the average price per square foot of a house in the United States each year for several years. A line of best fit for the data is also shown.
The line of best fit predicted that the average price per square foot in 2001 would be $76. What is the difference between the predicted value and the actual average price per square foot in 2001?
- $0
- $2
- $4
- $6
The correct answer is: $4
The predicted value of average price per square root = 76.
The actual value of average price per square root = 72.
The difference = 76 - 72 = 4.
