If you are interested in predicting life expectancy for babies born in a given year, which variable is the independent variable and which is the dependent variable?
Draw a scatter plot to determine if there appears to be a linear relationship between year of birth and life expectancy.
Fit a line to the data. Show your work.
Based on the context of the problem, interpret in words the intercept and slope of the line you found in part (c).
Use your line to predict life expectancy for babies born in New York City in 2010.
