Incinerators can be a source of hazardous emissions into the atmosphere. Stack gas samples were collected from a sample of 50 incinerators in Chicago. Of the 50 samples, only 18 met an environmental standard for the concentration of a hazardous compound. Can it be concluded that fewer than half of the incinerators in Chicago meet the standard
