Does alcohol consumption cause increased cravings for cigarettes? Research at Purdue University suggests this is so (see CNN.com web site article "Researchers Find Link Between Cigarette Cravings and Alcohol;' dated June 13, 1997). In an experiment, 60 heavy smokers and moderate drinkers were divided into two groups. One group drank vodka tonics and the other group drank virgin tonics (tonic water alone), but all subjects were told they were drinking vodka tonics. The researchers then measured the level of nicotine cravings (by monitoring heart rate, skin conductance, etc.). Those who had consumed the vodka tonics had $35 \%$ more cravings than those who did not. Assuming that the assignment of subjects to the treatment (vodka) and control groups was made at random, do you think there are any confounding factors that would make conclusions based on this experiment questionable?

Sustainable agriculture is a method of growing and raising food by taking advantage of natural biogeochemical cycles without disrupting them. Write down a question you have about sustainable agriculture and conduct a research project to answer your question. Use multiple sources to gather your information.

A researcher measures the amount of sugar in several cans of the same soda. The mean is 39.01 with a standard deviation of 0.5. The researcher randomly selects a sample of 100. Find the probability that the sum of the 100 values is greater than 3,910.

The Journal of Consumer Research (Aug. 2011) published a study demonstrating the "last name" effect- i.e., the tendency for consumers with last names that begin with a later letter of the alphabet to purchase an item before consumers with last names that begin with earlier letters. To facilitate the analysis, the researchers assigned a number, x, to each consumer based on the first letter of the consumer's last name. For example, last names beginning with "A" were assigned x = 1, last names beginning with "B" were assigned x = 2, and last names beginning with "Z" were assigned x = 26. Do you believe the probability distribution in part a is realistic? Explain. How might you go about estimating the true probability distribution for x?

Dimethyl mercury is an organic compound that poses a serious environmental threat to all living things. Research how this compound affects living things. Include information on whether dimethyl mercury poses a threat to your local environment. If so, determine what is being done to eliminate this problem.
