Fitting Linear Models to Data · Review Exercise 88

Consider this scenario: The population of a city increased steadily over a ten-year span. The following ordered pairs show the population and the year over the ten-year span (population, year) for specific recorded years:

$\left(\text{3},\text{6}00,2000\right);\left(\text{4},000,2001\right);\left(\text{4},\text{7}00,2003\right);\left(\text{6},000,2006\right)$

What is the correlation coefficient for this model to three decimal places of accuracy?

Its source prints no answer for this problem, so there's nothing to check against.
