  1. A researcher is looking at the amount of acres burned due to wildfires every year. She is concerned that global warming may be associated with an increase in the number of fires and the acres burned and wants to be able to predict how many acres might be burned if the number of fires increases. She collects data on the variables.

What is the predictor (independent x) variable? What is the response (dependent y) variable?

She computes a correlation ( r ) of .516. How much of the change in the dependent variable is explained by the independent variable?

Do you see anything that you might be concerned with in this research? Are there other variables that might be more effective to test?
