FIND P VALUE, X^2, DF ( DEGREE FREEDOM ) 

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. Region Northeast Midwest South West Past Year Observed Counts 155 232 395 218 Proportion 0.194 0.236 0.351 0.219 Send data to Excel Part 1 of 4 Can you conclude that the proportions of people living in the various regions changed between the current year and the past year? Use the 0.10 level of significance and the P-value method with the TI-84 Plus calculator. (a) State the null and alternate hypotheses. Ho: The proportions of U.S. residents who lived in each geographic region in the past year are current year. H₁: : The proportions of U.S. residents who lived in each geographic region in the past year are not current year. the same as those in the the same as those in the
