A stratified sample would be the best choice as it allows for the FAA to divide the departing jets into groups (strata) based on their noise level and then randomly sample from each group, ensuring that they are getting a representative sample across all levels of noise. This is important when assessing fines based on noise levels as they want to ensure they are accurately capturing the range of noise levels produced by departing jets.
