Consider an election with three candidates with the results:
(CBA) 2
(ACB) 6
(BAC) 5
(BCA) 2
Is there a majority winner? If not, who is the plurality winner? Answer No, B; Yes, A; No, A; No, C; or Yes, B.
Who wins the election using the Borda count method? Answer B; A; C and B tie; C; or A and B tie.
Who wins if they first eliminate the one with the most last-place votes and then have a runoff between the other two? Answer B; A; C and B tie; C; or A and B tie.
Could the two voters with preference (BCA) change the outcome of the election in previous question if they voted insincerely and pretended to have the preference (BAC)? Answer yes or no.
Majority Criterion and Borda Method
A group of teachers are planning a conference. They are
members of Teachers for Tomorrow. They are coming from four
different states. The choices for holding the conference are:
• Atlanta (A),
• Perdido (P),
• Biloxi (B), and
Panama City (C).
Below are the results of the votes of all the teachers.
• Use the Borda method to determine the location the teachers chose.
• Determine if the Borda method violates the majority criterion.

- The U.S. Census Bureau conducts annual surveys to obtain information on the percentage of the voting-age population that is registered to vote. Suppose that 713 employed persons and 613 unemployed persons are independently and randomly selected and that 338 of the employed persons and 244 of the unemployed persons have registered to vote. Can we conclude that the percentage of employed workers ( p1 ), who have registered to vote, exceeds the percentage of unemployed workers ( p2 ), who have registered to vote? Use a significance level of α=0.1 for the test. Step 1 of 6 : State the null and alternative hypotheses for the test. Step 2 of 6 : Find the values of the two sample proportions, pˆ1p^1 and pˆ2p^2. Round your answers to three decimal places. Step 3 of 6 : Compute the weighted estimate of p, p‾p‾. Round your answer to three decimal places. Step 4 of 6 : Compute the value of the test statistic.

Sandwiches are eliminated and Pizza moves up to get one more first place vote. Pizza is already the winner, with 8 votes. There is no need for an instant runoff. Salad is eliminated and Pizza moves up to get five more first place votes. Salad is eliminated and Pizza moves up to get four more first place votes.arrow_forwardAn election is held among four candidates (A, B, C, and D). Using a voting method we will call the "Yoshida Method ", the winner of the election is candidate A. Due to an irregularity in the original vote count a new election must be held. In the new election nearly everyone resubmitted the same preferences. There were three voters, whoever, who changed their ballots. In the original election they voted "D first, then A second, then B third, then C last," but in the second election they promoted A to vote "A first, D second, B third, C last." In the recount, still using voting method X, candidate B wins the election. Based on the above information, we have just witnessed that the Yoshida Method violates the _______ criterion.
