Suppose the environmental protection agency asks you to help it understand the causes of urban pollution. Air pollution problems are worse the higher the air quality index gets. You develop the following two hypotheses. Hypothesis one: air pollution will be a greater problem as the average temperature increases in an urban area. Hypothesis two: air pollution will be a greater problem as the pollution increases in an urban area. Test each hypothesis with the data given in the following table. Which hypothesis fits the facts better? Have you developed a theory?
