Question: Nicotine in Cigarettes Refer to the nicotine contents of cigarettes listed in Data Set CIGARET.XLS (in the References, Media and Data Files section of the course). Use the sample data to test the claim that the population mean is less than 1.0 mg. Does the conclusion apply to the mean nicotine level of all 100 mm cigarettes (not menthol or light) smoked by consumers? Why or why not? Use a significance level of 0.05.
