3. Problem 3UG: The wealth in billions of dollars for 232 billionaires is given in fortune. (a) Plot the wealth as a function of age using a different plotting symbol for the different regions of the world. Comment on your results. (b) Repeat the plot of the previous question using a separate panel for each region. (c) Determine a transformation on the response to facilitate linear modeling. (d) What is the relationship of age and region to wealth? Use sequential ANOVA to deter- mine the best model. Interpret your results. (e) Check the assumptions of your model using appropriate diagnostics. Consider the possi- bility of unusual observations and remove these observations if necessary before re-fitting your model
