13 6 points Earthquakes come in three main forms, depending on the plate movements that occur beneath the earth's surface. They could occur on a Convergent Boundary, on a Divergent Boundary or on a Transform Fault. The severity of the earthquake is classified as either mild, moderate, or major. Of interest is to determine if there is a relationship between the form of the earthquake and the severity of the earthquake. A random sample of 500 earthquakes was analyzed, and the following chart presents the conditional distributions of the severity of the earthquake for each form of earthquake Convergent Boundary Divergent Boundary Transform Fault Mild 67% Mild 65% Mild 95% Moderate 23% Moderate 26% Moderate 3% Major 10% Major 9% Major 2% Since the conditional distributions are significantly different, there is an association between the form of the earthquake and the severity of the earthquake Since the conditional distributions are significantly different, there is not an association between the form of the earthquake and the severity of the earthquake. Since the conditional distributions are not significantly different, there is an association between the form of the earthquake and the severity of the earthquake. Since the conditional distributions are not significantly different, there is not an association between the form of the earthquake and the severity of the earthquake. Next Previous
