Comparison of the Performances of Different Types of Smoking Machines/Vergleich der Messgenauigkeit von Rauchmaschinen
The performances of smoking machines of different types cannot be compared directly if different numbers of cigarettes are smoked into one trap, because the respective variabilities are depending on the number of cigarettes smoked into one trap. For the comparison of means, the t-test can therefore...
