Statistics and Probability

There are many interesting statistics with regard to recycling. Recycling one aluminum can save enough energy the equivalent of a half-gallon of gasoline, to run a television for three hours. Because Americans have done such a good job of recycling aluminum cans, they account for less than 1% of the total U.S. waste stream. Recycling 1 pound of steel saves enough energy to run a 0-watt light bulb for over a day. On average, one American uses seven trees a year in paper, wood and other products made from tree. In addition, Americans use 680 pounds of paper per year. Each ton of recycled paper saves about 17 trees .380 gallons of oil, 3 cubic yards of landfill space, 4000 kilowatts of energy and 7000 gallons of water. Americans use 2.5 million plastic bottles every hour and throw away 25 billion Styrofoam cups every year. The energy saved from recycling one glass bottle can run a 100-watt light bulb for four hours. Every year, each American throws out about 1200 pounds of organic garbage that could be composted. The U.S. is number one in the world in producing trash, with an average of 1609 pounds per person per year. Answer the following:

a. The average person in the U.S. produces 1609 pound of trash per year. What additional information could be gleaned by also knowing the measure of variability on these data (pound of trash)? (2.5)

b. On average, one American uses seven trees a year in products. What different information median yield on these data and how might it help decision makers? (2.5)
