2. In a study of ground motion caused by earthquakes, the peak velocity in meters per second and peak acceleration in meters per second squared were recorded for five earthquakes. The correlation coefficient between velocity and acceleration was found to be, r = -0.8028. a. What does the value of the correlation coefficient tell you about the relationship between the two variables? b. You graphed the two variables and produced the following scatterplot (next page). In looking at the scatterplot, is the correlation coefficient an appropriate summary for these data? 8.5 7.5 6.5 Acceleration in on in 1.5 2.5 3.5 Velocity c. Someone suggests converting the units from meters to centimeters and from seconds to minutes. Would this have an effect on the correlation
