Professor Li is running for dog catcher. To win, she'll need at least 51% of the vote, or there will need to be a run-off. Her campaign manager did a survey and found that 210 of the 400 voters said they'd vote for her. While she is the underdog, she is sure she will win. Devise a hypothesis test where a = .05 a) State the Null and Alternate Hypothesis. b) Which test statistic does the data call for (which distribution)? Explain why you chose that distribution. c) State Decision Rule and Critical Value.
