2. In a study of smoking and its effects on sleep patterns, one variable is the time that it takes to fall asleep. A random sample of size 12 is drawn from the population of smokers; an independent sample of size 15 is drawn from the population of non-smokers.

Green and black tea are both derived from the same plant, Camellia sinensis. Green tea is produced by lightly steaming fresh-cut leaves. Black tea is made by allowing the leaves to oxidize, thereby converting highly therapeutic polyphenols such as epigallocatechin gallate (EGCG) to less active compounds. These polyphenols have potent antioxidant and anticarcinogenic properties. Two brands of green tea were analyzed for their concentrations of EGCG (in mg/cup).
