Voter Turnout. Minnesota had the highest
turnout rate of any state for the 2016 presidential election.
(United States Election Project website) Political analysts wonder
if turnout in rural Minnesota was higher than turnout in the urban
areas of the state. A sample shows that 663 of 884 registered
voters from rural Minnesota voted in the 2016 presidential
election, while 414 out of 575 registered voters from urban
Minnesota voted.
- 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
2016 presidential election.
- What is the proportion of sampled registered voters in rural
Minnesota that voted in the 2016 presidential election?
- What is the proportion of sampled registered voters in urban
Minnesota that voted in the 2016 presidential election?
- At α = 0.05, test the political analysts' hypothesis. What is
the p-value and what conclusion do you draw from your results?
