By law, an industrial plant can discharge not more than 500 gallons of waste water per hour, on the average, into a neighboring lake. Based on other infractions they have noticed, an environmental action group believes this limit is being exceeded. Monitoring the plant is expensive, and only a small sample is possible. Four one-hour periods are selected randomly over a period of one week. The following are observed:
1384, 683, 1534, 405
