Earthquakes occur when energy is released from deep inside the earth, causing friction between the tectonic plates of the earth's crust. The magnitude, or intensity, of the earthquake is measured on the Richter scale. The scatterplot above shows the earthquakes experienced by California between December 2003 and December 2010. The line of best fit, which has a slope of 0, is a fairly good indicator in California. Approximately what percent of the earthquakes in California during this time period differed by 1 point or more on the Richter scale from the magnitude predicted by the line of best fit?
A. 22%
B. 27%
C. 33%
D. 36%
