When an election for political office takes place, the TV cancels all regular programming and instead provide election coverage. For important offices such as the President of the US, the networks actually compete to determine who will be the first to predict a winner. This prediction is carried out via “exit polls” wherein a random sample of voters exiting the polling booth is asked for whom of the two candidates they voted. Based on the data, a statistical model (which can vary from station to station) is applied to determine whether there is sufficient evidence to infer that the leading candidate identified in the “exit poll” will gather sufficient votes to win. In a particular election, the “exit poll”survey for a particular network indicated that 407 of the 765 voters polled said that they had voted for candidate A. The polls close at 8:00 PM. At confidence level 0.95, what is the test statistic for winning candidate?
