Polynomial Regression Analysis
Use a polynomial model for the data to answer the following questions. Round all numerical answers to 3 decimal places, and years to the year.
1. Today, how many square kilometers of the earth’s surface are there per person? If this were a square, what would be the length of one side?
2. If the population continues to grow at the current rate, in what year will we have an average of one thousand square meters of the earth’s surface per person (assuming everyone can walk on water?
3. Assuming that no one can walk on water, no one wants to live in Antarctica and correct for the uninhabitable land, repeat question #2.
4. Assuming the present population growth rate was the same in the past, in what year did we have only two people on earth? Is this realistic?
