Use the magnitudes (Richter scale) of the earthquakes listed in Data Set 16 in Appendix B. In 1989, the San Francisco Bay Area was struck with an earthquake that measured 7.0 on the Richter scale. That earthquake occurred during the warm-up period for the third game of the baseball World Series. Is the magnitude of that World Series earthquake an outlier (data value that is very far away from the others) when considered in the context of the sample data given in Data Set 16? Explain.

Data Set 16: Earthquake Measurements Fifty matched pairs of magnitude/depth measurements randomly selected from 10,594 earthquakes recorded in one year from a loca- tion in southern California. MAG is magnitude measured on the Richter scale and DEPTH is depth in km. The magnitude and depth both describe the source of the earthquake. In the two tables below, magnitudes and depths are paired by their corresponding positions in the two tables. The data are from the Southern California Earth- quake Data Center.
