A severe eаrthquаke hаs an average magnitude оf 6.2 оn the Richter scale. Suppоse a region is experiencing a series of aftershocks following a severe earthquake. Let us say that we want to set up a statistical test to determine if the seismic activity (i.e., magnitude) is decreasing or increasing. If you wanted to test the hypothesis that the aftershocks are decreasing in magnitude, what would you use for the alternate hypothesis? Is the P-value area on the left, right, or on both sides of the mean?
