Refer to Table 11-1, used for the chapter problem. This table includes paired data representing the recorded latitudes and magnitudes of seismic activity (earthquakes). These data can only be recorded if an earthquake is picked up by monitors, and the great majority of these are located in Canada's lower latitudes. If it is possible that the widely spaced monitors in northern Canada are failing to detect lower-magnitude earthquakes in those latitudes, what effect could this have on our interpretation of this chapter's correlation results?
