Fitting Linear Models to Data · Exercise 118

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

$(\text{4},\text{500},\text{2000});(\text{4},\text{700},\text{2001});(\text{5},\text{200},\text{2003});(\text{5},\text{800},\text{2006})$

Use linear regression to determine a function y, where the year depends on the population. Round to three decimal places of accuracy.
