Assume the carrying capacity of the earth is 15 billion. Use the 1960s peak annual growth rate of 2.1 ​% and population of 3 billion to predict the base growth rate and current growth rate with a logistic model. Assume a current population of 6.8 billion. How does the predicted growth rate compare to the actual growth rate of about 1.2 ​% per​ year? What is the base growth​ rate?

​(Round to four decimal places as​ needed.)
What is the estimated current growth​ rate?
