Also what is the p-value

The air in poultry-processing plants often contains fungus spores that can affect the health of workers. To see if ventilation changes should be implemented based on the season, air samples collected from each season were pumped onto agar plates and tested for colony-forming units (CTUs per cubic meter of air). The results are shown below.
