The population of the US in 1800 and 1850 was 5.3 and 23.1 million people respectively.

Predict its population in 1900 and in 1950 using the exponential model of population growth.

Then considering that the population of the US in 1900 was actually 76 million people correct your prediction for 1950 using the logistic model of population growth (help: with this data r = 0.031476 yr-1 in the logistic model). What is the carrying capacity of the US according to this model and what is the new prediction for 1950?
