World Population A 2005 United Nations population study reported the world population between 1804 and 1999 and projected the population through 2183. These population figures are shown in the table.

a. Align the output data by subtracting 0.9 from each value and align input so that x = 0 in 1800. Use the

aligned data to find a logistic model for world population. Discuss how well the equation fits the data.

b. Use the model to estimate the world population in 1900 and in 2000. Are the estimates reliable? Explain.

c. According to the model, what will ultimately happen to world population?

d. Do you consider the model appropriate to use in predicting long-term world population behavior?
