Consider an election with 301 voters cast for 3 candidates. What is the smallest number of first-place votes that a candidate can receive to win by the Plurality method?
A Pre-Election Survey to 2400 respondents was commissioned by SWS Asia on people’s choice to become the next President and Vice President for the upcoming 2022 Elections. 877 of them prefer the PoGo tandem (Grace Poe and Bong Go), while 948 chose team DutDut (Sara and Rodrigo Duterte) and 25 prefer Ocho Diretso’s standard bearer, the LeChe tandem (Leni Robredo and Chel Diokno). Meanwhile, 253 respondents prefer both PoGo and DutDut, 18 prefer both PoGo and LeChe while a surprising 5 respondents chose both DutDut and LeChe. 3 respondents prefer any of the tandems to win in the elections. How many respondents who chose not to vote on these tandems?
Do U.S census bureau conducts annual survey to obtain information on the percentage of the voting age population that is registered to vote. Suppose that 385 employed person and 473 unemployed persons are independently and randomly selected, in that 202 of the employed persons and 185 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 an unemployed workers (P2), who have registered to vote? Use a a significance level of a= 0.1 for the test.

- An 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.
