The Occupational Safety and Health Act (OSHA) allows issuance of engineering standards to ensure safe workplaces for all Americans. The maximum allowable mean level of arsenic in smelters, herbicide production facilities, and other places where arsenic is used is .004 milligram per cubic meter of air. Suppose smelters at two plants are being investigated to determine whether they are meeting OSHA standards. Two analyses of the air are made at each plant, and the results (in milligrams per cubic meter of air) are shown in the table. A claim is made that the OSHA standard is violated at Plant 2 but not at Plant 1. Do you agree?
