Question: Do you Tweet? In early 2012, the Pew Internet and American Life Project asked a random sample of U.S. adults, "Do you ever use Twitter or another service to share updates about yourself or to see updates about others?" According to Pew, the resulting 95% confidence interval is (0.123, 0.177). Does this interval provide convincing evidence that the actual proportion of U.S. adults who would say they use Twitter differs from 0.16? Justify your answer.
