This Web project will take approximately two weeks to complete. The U.S. Census Bureau has two population clocks on its Web page (www.census.gov). One gives the estimated current U.S. popu lation, and the other gives the estimated current world population.

a. Visit this site at two different times approximately one week apart, and record the time and the population (either U.S. or world population). Use these two different ordered pairs to create an exponential model, where t is time in hours.

b. Use the exponential model to predict the population approximately one week into the future.

 c. Revisit the Census Bureau’s website at the appropriate time to compare your prediction from part (b) with the actual population. What is the error in your prediction? That is, what is the difference between your prediction and the actual population?

d. What is the percent error in your prediction? To find this percent error, take the error from part (c), divide it by the actual population, and convert the result to a percent.
