Research an Economic Term. The student text describes both commodity money and fiat money. Another term that is used to describe a type of money is representative money. This term is defined differently by different people. Some use this term to only identify a claim on a commodity money (such as a document that represents or "stands in place of" actual gold). Others use this term to denote any money where the face value of the money (the $5 or$10 say, written on the face (front) of the money) represents a greater value than the value of the material. Go online and find examples of people using this term. Then, using your research to support your view, describe representative money in your own words

As Americans become more conscious of the importance of good nutrition, some researchers believe that we may be eating less red meat. To test this theory, a researcher decides to select hospital nutritional records for subjects surveyed 10 years ago and to compare the average amount of beef consumed per year to the amounts of beef consumed by an equal number of subjects she will interview this year. She knows that the amount of beef consumed annually by Americans ranges from 0 to approximately 104 pounds. How many subjects should the researcher select for each group if she wishes to estimate the difference in the average annual per-capita beef consumption correct to within 5 pounds with 99% confidence?
