The goal of this study was to develop a model for predicting the number of species from the island size.
a. Which is the response variable in this study?
The following scatterplots show least squares lines for predicting number of species from island size, first without a transformation and then taking log (base 10) of both variables:
b. Which model would you use? Explain your choice.
c. Use the model that you chose to predict the number of species on an island with a size of 2000 square miles.
