Chapter 12, Problem T12.10

(choose chapter or problem)

We record data on the population of a particular country from 1960 to 2010. A scatterplot reveals a clear curved relationship between population and year. However, a different scatterplot reveals a strong linear relationship between the logarithm (base 10) of the population and the year. The leastsquares regression line for the transformed data is log (population) = 13.5 + 0.01(year) Based on this equation, the population of the country in the year 2020 should be about (a) 6.7. (c) 5,000,000. (e) 8,120,000. (b) 812. (d) 6,700,000. T12
