China's carbon dioxide emissions from the burning of fossil fuels have grown rapidly for many years. An exponential regression model was calculated to predict y = CO2 emissions from fossil fuels (in metric tons) from x = years since
1902. The regression equation is y = 5,250,100(1.072)^x. In 1962 (x =60), China's CO2 emissions totaled 440,319,000 metric tons. Which of the following is the residual for this observation?
a) - 340,294,317.5
b) - 100,024,682.5
c) 100,024,682.5
C) 340,294,317.5
