What effect does noise pollution have? Mathews and Canon (1975) had a person with a cast on one arm get out of a car and drop an armload of books in front of pedestrians. Will the pedestrians help? Maybe. Sometimes there was a loud gasoline lawn mower operating nearby when the books were dropped and sometimes the mower was not operating. These data mimic their results. Of the 25 pedestrians who could have helped when the mower was operating, four did so. Of the 25 who could have helped when the mower was quiet, 20 did so. Analyze the numbers and write an explanation of the effects of noise pollution. Of the 25 pedestrians who could have helped when the mower was operating, four did so.
