The U.S. Census Bureau computed the proportion of U.S. residents who lived in each of four geographic regions in 2010. Then a simple random sample was drawn of 1000 people living in the United States in 2017. The following table presents the results: 2010 Proportion 2017 Frequency 0.179 173 0.217 205 0.371 384 0.233 238 Northeast Midwest South West Can you conclude that the proportions of people living in the various regions changed between 2010 and 2017? Use the 0.05 level of significance.
