Refer to the accompanying datatable, which shows the amounts of nicotine (mg per cigarette) in king- sigarettes, 100 menthol cigarettes and 100-mm nonmental cigarettes. The king-size cigarettes are no litered, while the 100-mm menthol cigarettes and the 100-mm nonmenthol cigarettes are flered. Use a 0.06 significance level to test the claim that the three categories of cigarettes yield the same man amount of nicotine. Given that only the king size cigarettes are not fired, do the Stars appear to make...
