In Example 1 on page 731, we used two data points and an exponential function to model the population of the United States from 1970 through 2009. The data are shown again in the table. Use all five data points to solve Exercises 4549. x, Number of Years after 1969 y, U.S. Population (millions) 1 (1970) 203.3 11 (1980) 226.5 21 (1990) 248.7 31 (2000) 281.4 40 (2009) 307.0Use your graphing utilitys logarithmic regression optionto obtain a model of the form y = a + b ln x that fits thedata. How well does the correlation coefficient, r, indicatethat the model fits the data?
