Fit a regression line to the data shown in the chart, and find the coefficient of correlation for the line. Use the regression line to predict life expectancy in the year 2010, where x is the number of decades after 1900.
0 (1900)
year, x
2 (1920) 4 (1940) 6 (1960) 8 (1980)
life expectancy, y 49.8 years 52.1 years 53.7 years 54.9 years 55.9 years
Choose the correct regression line below.
A. y = 50.28
O B. y = 0.750x + 50.28
y = 0.750x – 50.28
O D. y = 50.28x + 0.750
The coefficient of correlation is
(Round to three decimal places as needed.)
The life expectancy in the year 2010 is
(Round to one decimal place as needed.)
