Question: Many scientists have warned that global warming is causing the polar ice caps to melt and, therefore, sea levels around the world to rise. 415

Many scientists have warned that global warming is causing the polar ice caps to melt and, therefore, sea levels around the world to rise. 415 random samples of the sea level (in millimeters) at Rockport, Massachusetts, from 1987 to 2011 were obtained and are summarized in the following table. The level was measured to the nearest millimeter.
