Minnesota had the highest turnout rate of any state for the 2012 presidential election. Political analysts wonder if turnout in rural Minnesota was higher than turnout in the urban areas of the state. A sample shows that 645 of 860 registered voters from rural Minnesota voted in the 2012 presidential election, while 414 out of 575 registered voters from urban Minnesota voted. (a) Formulate the null and alternative hypotheses that can be used to test whether registered voters in rural Minnesota were more likely than registered voters in urban Minnesota to vote in the 2012 presidential election. (Let Pa = the population proportion of voters in rural Minnesota who voted in the 2012 election and pz = the population proportion of voters in urban Minnesota who voted in the 2012 election.) o Ho: P1-P250 Ha: P1 - P2 > 0 Ho: P1-P2 = 0 H: P.-P20 Ho: P2 - P220 H: P1 - P20 HP - P20 H: P1 P2 = 0 o Ho: P1-P270 HP1-P2 = 0 (b) What is the proportion of sampled registered voters in rural Minnesota that voted in the 2012 presidential election? (c) What is the proportion of sampled registered voters in urban Minnesota that voted in the 2012 presidential election? (d) At a = 0.05, test the political analysts' hypothesis. Calculate the test statistic. (Round your answer to two decimal places.) What is the p-value? (Round your answer to four decimal places.) p-value = What conclusion do you draw from your results? Reject H. We can conclude that voters from rural Minnesota voted more frequently than voters from urban Minnesota in the 2012 Presidential election. O Reject H. We cannot conclude that voters from rural Minnesota voted more frequently than voters from urban Minnesota in the 2012 Presidential election. O Do not reject Ho. We cannot conclude that voters from rural Minnesota voted more frequently than voters from urban Minnesota in the 2012 Presidential election. Do not reject H . We can conclude that voters from rural Minnesota voted more frequently than voters from urban Minnesota in the 2012 Presidential election.
