C12. The 2018 average life expectancy for the total population is reported for 10 countries. Calculate the appropriate measures of central tendency and variability for both European countries and non-European countries. Is there more variability in life expectancy for European countries or non-European countries? If so, what might explain these differences?

Use the table that shows the life expectancy for people born in various years. $\begin{array}{|c|c|c|c|c|c|}\hline 1950 & {1960} & {1970} & {1980} & {1990} & {2000} \\ \hline 68.2 & {69.7} & {70.8} & {73.7} & {75.4} & {7.0} \\ \hline\end{array}$ Predict the life expectancy of a person born in 2010.

The table below gives the average life expectancy (in years) of a person from a certain country based on various years of birth. Use a TI-83, TI-83 plus, or TI-84 calculator to find the equation of the regression line, using the year as the independent variable and the average life expectancy as the dependent variable. Round the slope and intercept to one decimal place.
