Instructions: Let's investigate some large numbers that play key roles in all our lives. Use the Web to find the numbers you need to answer the following questions, cite the websites you use. Check to see if the numbers you find in steps 2, 3, and 4 are consistent with the population cited in step 1 and discuss any discrepancies. Post your answers in a new thread in this discussion (note, you will not be able to see other's posts until you have initially posted your response). You may find that you and your colleagues find different results; if that happens, discuss how each of you found your numbers, why they differ, and which estimate is likely to be the best one. For full credit on this assignment, you must post your initial responses to the questions and respond to at least one other student discussing differences in your responses and their responses. 1. What are the current populations of the United States and the world? What fraction of the world's population lives in the United States? 2.
