9. The table below shows the life expectancy for an individual born in a country in certain years. g) h) j) Year of Birth Life Expectancy Year of Birth Life Expectancy 1930 59.7 1940 62.9 1950 70.2 1965 69.7 1973 71.4 1982 74.5 1987 75 1992 75.7 2010 78.7 Decide which variable should be the independent variable and which should be the dependent variable. Draw a scatter plot of the ordered pairs. Calculate the regression (least-squares; best-t) line. Find the correlation coefcient. Is it signicant? Find the estimated life expectancy for an individual born in 1950 and for one born in 1982. Why aren't the answers to part (e) the same as the values in the table above that correspond to those years? Based on the data, is there a linear relationship between the year of birth and life expectancy? Are there any outliers in the data? Using the least squares line, nd the estimated life expectancy for an individual born in 1850. Does the least-squares line give an accurate estimate for that year? Explain why or why not. What is the slope of the least-squares (best-t) line? Interpret the slope
