Question

Transcribed Image Text:A random sample of 25 brand A cigarettes shoed an average nicotine content of 5 milligram, while a sample of 40 brand D cigarette showed an average nicotine of 4.8 milligram. If the standard deviation of nicotine is 1.6 milligrams, would you say that brand D has a lesser nicotine content? Use a 0.01 level of significance. Assume the distribution of nicotine content to be normal.
