2016 Irish Exit Poll The 2016 General Election Exit Poll was conducted exclusively by Ipsos MRBI, on behalf of The Irish Times. It took place among a national sample of 5260 voters across 200 polling stations throughout all constituencies in the Republic of Ireland. For two candidates, Fine Gael and Fianna Fáil, the parties’ vote shares were 26.1% and 22.9%, respectively.

b. Suppose the sample size had been 500 voters, with the same sample proportions given above. What will be the new test statistic and P-value? Will you now be willing to predict the outcome of the election?
