Unformatted text preview: relationship to look like? (answer this before you look at the data) 2. (10 points) What is the linear correlation between the proportion of exotic species and the per-capita GDP? 3. (25 points) Write down a regression equation relating these two variables. Identify: a. The dependent and independent variables b. The parameters c. The residuals 4. (25 points) Use the software of your choice to estimate the parameters of the model you developed in (3). Report each of the quantities we discussed in class: coefficient of determination, parameter estimates and their uncertainties, standard deviation of the residuals, and P-values (state what those P-values represent). Don’t simply paste the output of the software into your report. 5. (25 points) Use the results from part 4 to answer the question, “All else being equal, if a country’s per-capita GDP doubled from $5000/person to $10000/person, by how much would we expect the fraction of exotic species to increase?”...
