Census data for the United States between 1790 and 1950 are given in the table above. Construct a logistic population model usi 90. (Assume that this years since 1790 and P is population in millions. Round all coefficients to four decimal places.) Construct a table comparing actual census population with the population predicted by the model in part (a). Compute the error a

(a) Census data for the United States between 1790 and 1950 are given in the table above. Construct a logistic population model using the data from 1790, 1840, and 1890. (Assume that this years since 1790 and P is population in millions. Round all coefficients to four decimal places.) P(t) = (b) Construct a table comparing actual census population with the population predicted by the model in part (a). Compute the error and the percentage error for each entry pair. Year 1820 1850 Census Population (in Millions) 9.638 23.192 Predicted Population (in Millions, rounded to three decimal places) Error (rounded to three decimal places) % Error (rounded to two decimal places) % %
