question 2

Multiple Choice

Is the magnitude of an earthquake related to the depth below the surface at which the quake occurs? Let x be the magnitude of an earthquake (on the Richter scale) , and let y be the depth (in kilometers) of the quake below the surface at the epicenter. Suppose a random sample of earthquakes gave the following information. Would you say the correlation is low, moderate, or strong? Positive or negative? If necessary, draw a scatter diagram of the given data.
