As of this writing, the U.S. Bureau of the Census used its own model to predict a population of 420 million for the United States in 2050. Use the data in Table 10-9 on page 571 to find the value of R² and the 2050 projected population for the linear, quadratic, logarithmic, exponential, and power models. Do any of the models yield a projected population close to 420 million in 2050?
