This dataset contains the results from a study where 12 rats (rat) that were exposed to ozone at the rate of 2 parts per million over a period of 30 days. The lung capacity of each rat was determined at the beginning of the study and again after 30 days of ozone exposure (time). The lung capacities are provided in milliliters (resp).
