A government agency computed the proportion of U.S. residents who lived in each of four geographic regions in a particular year. Then a simple random sample was drawn of 1000 people living in the United States in the current year. The following table presents the results. Past Year Observed Region Proportion Counts Northeast 0.181 152 Midwest 0.248 227 South 0.343 390 West 0.228 231 Send data to Excel Can you conclude that the proportions of people living in the various regions changed between the current year and the past year? Use the 0.01 level of significance and the P-value method with the TI-84 Plus calculator. Part: 0 / 4 Part 1 of 4 (a) State the null and alternate hypotheses.
