Problem 5

Population 3: Figure 8-4j and thetable below show the population of the United States for various years. The information was obtained from the U.S. Census Bureau at www.census.gov. The variable x is the number of years elapsed since 1930. 1940 10 132.1 1950 20 152.3 1960 30 180.7 1970 40 205.1 1980 50 227.2 1990 60 249.5 Figure 8-4j a. Explain why a linear function and an untranslated power function would not have the correct endpoint behavior for dates long before 1930. Explain why an exponential function of the form y = abx would not have a reasonable endpoint behavior for dates long after the present. b. Find the particular equation of the bestfitting logistic function. Plot it and the data on the same screen. Use a window that includes dates back to 1830 and forward to 2130. Sketch the result. c. What does the logistic model predict for the outcome of the 2000 census? (You can check the Web site to see how close this comes to the actual outcome.) What does the logistic model predict for the maximum sustainable population of the United States? d. Suppose that the result of the 1990 census had been 250.5 million, one million higher. Run another logistic regression with the modified data. What does the new model predict for the maximum sustainable population?
