Factors: Ozone and sulfur dioxide
Factor levels: Ozone will have 3 (0 ppb, 100 ppb, and 200 ppb)
Sulfur dioxide will have 2 (0 ppb and 75 ppb)
Treatment Combinations: 2 x 3 = 6 (in a complete factorial design)
Replications: 6 observations at each treatment combination (balanced design).
Ho - ozone and sulfur dioxide harm lung tissue.
Ha - ozone and sulfur dioxide don’t harm lung tissue.
