A Gallup poll from December of 2009 asked whether U.S. residents who are aware of climate change thought their government was doing enough to reduce emissions of cars and factories. Gallup estimated that 52% of all such U.S residents felt that the government was not doing enough. If another poll were taken and there were 500 participants, how many would you expect to say that the United States was not doing enough, assuming the percentage remained the same?
