Confidence in banks: A poll conducted in 2012 asked a random sample of 1268 adults in the United States how much confidence they had in banks and other financial institutions. A total of 144 adults said that they had a great deal of confidence. An economist claims that less than 11% of U.S. adults have a great deal of confidence in banks. Can you conclude that the economist's claim is true? Use both =α0.05 and =α0.10 levels of significance and the P-value method with the TI-84 Plus calculator.
