17.38 Fungus in the air. The air in poultry-processing plants often contains fungus spores. Inadequate ventilation can affect the health of the workers. The problem is most serious during the summer. To measure the presence of spores, air samples an incubation period. Here are data from two locations in a plant that processes are pumped to an agar plate and "colony-forming units (CFUs)" are counted afte 37,000 turkeys per day, taken on four days in the summer. The units are CFUS per cubic meter of air. 20 Kill room Processing Day 1 3175 529 Day 2 2526 141 Day 3 1763 362 (a) Explain carefully why these are matched pairs data.
