Census data for the United States between1790 and 1950 are given in Table. Construct a logisticpopulation model using the data from 1790, 1850, and 1910.(b) Construct a table comparing actual census populationwith the population predicted by the model in part (a).Compute the error and the percentage error for each entrypair.
Suppose that a population follows a logistic growth model. The population in the first year is 21.7 thousand. In the second year the population has increased by 54 hundred. In the third year, the population has increased by 17 hundred.
Find the carrying capacity of the population.

- The table shows the mid-year populations (in millions) of five countries in 2015 and the projected populations (in millions) for the year 2025.
