A climatologist has been collecting sulfur dioxide readings from a sample of monitoring sites located at several different distances downwind from a coal-burning power plant. She suspects that the farther downwind a location is from the plant, the lower the sulfur dioxide concentration will be. Is this a statistically significant relationship? The Research Hypothesis is: Slope< 0 Slope 0 Slope= 0 Slope> 0 Slopes 0 Slopez 0
