ff data gives the approximate population of China from 1990-2010 Year 1900 1950 1970 1980 1990 2000 2010   Population 400 557 825 981 1153 1266 1370 Assume that the population growth can be modeled with an exponential function p = bemx , where x is the year and p is the population in millions. Write the equation in a linearized form of the equation, e.g. ln p = ln b + mx, and use linear least-squares regression (here you can use Excel) to determine the constants b and m for which the function best fits the data. Use the equation to estimate the population in the year 1985.
