Im kind of confused on this question?? To help consumers assess the risks they are taking, the Food and Drug Administration (FDA) publishes the amount of nicotine found in all commercial brands of cigarettes. A new cigarette recently been marketed. The FDA tests on this cigarette gave a mean nicotine content of 26.7 milligrams and standard deviation of 2.2 milligrams for a sample of n = 9 cigarettes. The FDA claims that the mean nicotine content exceeds 30.2 milligrams for this brand of cigarette,
and their stated reliability is 99%. Do you agree? Explain.

I too am confused. The FDA's tested mean is below their "standard" of 30.2. How could they possibly conclude the acutual mean above 30.2??
