The U.S. Census Bureau computed the proportion of U.S. residents who lived in each of the four geographic regions in the year 2000. There were 19% in the Northeast, 22.9% in the Midwest, 35.6% in the South and 22.5% in the West. Then a simple random sample was drawn of people living in the U.S. in 2011. Can you conclude the distribution in where people live in the U.S. has changed from 2000 to 2011? Use a 5% significance to decide. Round to the fourth as needed.
