In 2009 news organizations reported that 47% of U.S. adults favored providing a legal way for illegal immigrants already in the U.S. to become citizens. In 2010, the percentage with this opinion rose to 50%. Suppose that a current poll of 1000 randomly selected U.S. adults shows that 530 favor providing a legal way for illegal immigrants already in the U.S. to become citizens.Perform a hypotheses test at a 1% level of significance to investigate if the sample provides enough evidence to conclude that the the proportion of U.S. adults who favor a legal way for illegal immigrants to become citizens has increased from 50%.
