The correlation coefficient is 0.994, which indicates a strong correlation. However, the residual plot indicates that while the residuals are small, there may be a pattern to the data.

So, it will be important to also check exponential functions. In the context of the problem, an exponential model may make sense, as population data is typically exponential in nature.
