Finding the Equation
Interpolation Question
What would the median age be if the life expectancy was 69?
Extrapolation Question
What would the median age be if the life expectancy was 100?
As the income per person increases by $1.00, the life expectancy also increases by 2.08 years. It is a positive correlation.
The initial value is 45.94. So if the median age is 0 the life expectancy increases by 45.94.
