Are cigarettes bad for people? Cigarette smoking involves tar, carbon monoxide, and nicotine (measured in milligrams). The first two are definitely not good for a person's health, and the last ingredient can cause addiction.

reporter wants to test whether the mean nicotine content is
actually higher than advertised. He takes measurements from a SRS
