Suppose that you work for the conservation of natural areas at the Bureau of Land Management. Your section concerns the effect of wildfires on natural areas. Your supervisor asked you to analyze the temporal trend in wildfires. In particular, she is interested in the following associations: Has the number of wildfires per year increased? Has the total burned area (in acre) per year increased? Has the burned area (in acre) per fire increased? The accompanied data file contains the number of wildfires, total burned area, and burned area per fire in the U.S. from 2000 to 2019. Question 7. Based on the coefficient of determination you calculated in Question 3, what percentage in the variability in the dependent variable is explained by year? Refer to the textbook 12.3. (10 pts.)
