Use your graphing calculator’s logarithmic regression option (LnReg) to obtain a model of the form that fits to the data. Use the function to find the US population in 2010. Round to the nearest tenth of a million. Does this function value overestimate or underestimate the US population in 2010 given in the table? By how much? According to the logarithmic regression model, when will the US population be 400 million?
