Still do not delete your L, and L, from before. Also do not delete your M and your B. The line Y=M*X+B can be used to predict the US population Y in any given year X. (The prediction may not be a good prediction but we can worry about that later.) You can use your calculator to get all the population predictions for the years in our original table: store M*L,+B as L3 The line predicts that in 1810 the US population was The line predicts that in 1890 the US population was The residuals are the differences 'actual value' minus 'predicted value' You can now easily get the residuals by storing L,-L3 as L4 The residual for 1850 is

The following table gives the US population (in thousands) from 1790 to 2010: 1790: 3929 1810: 7240 1830: 12866 1850: 23192 1870: 39818 1890: 62948 1910: 91972 1930: 122775 1950: 150697 1970: 203302 1990: 248710 2010: 308746 Enter the years into L, and the populations into L2 (in the same order). Produce a scatterplot. Does the scatterplot seems to follow a line? Explain your thinking clearly
