Is a linear model appropriate for these data? Justify your answer. Below is a scatterplot of the natural logarithm of cell phone subscribers vs. year. This relationship is clearly more linear that the one above. Does this suggest that the relationship between cell phone subscribers and year can be modeled by an exponential function or by a power function? Explain.
