The human population (in thousands) of Nevada in 19501950 was roughly 160.160. If the carrying capacity is estimated at 1010 million individuals, and assuming a growth rate of 2%2% per year, develop a logistic growth model and solve for the population in Nevada at any time (use 19501950 as time = 0). What population does your model predict for 2000?2000? How close is your prediction to the true value of 1,998,257?1,998,257?
