In the manufacture of a specific type of cigarette, a nicotine content (in mg) of po=12 are not exceeded. We assume that the nicotine content is normally distributed. For regular control, test random samples of 20 cigarettes each are taken from a production lot and the nicotine content is determined. The arithmetic mean was obtained for a test samplex= 12.14 and the sample standard deviations(x) = 1.5. Are the data consistent with the assumption that the target value0=12 is not exceeded in the overall production on average? Test to levela= 5%.
