Question Set 1. Exit Poll Results

As a random sample of voters are leaving their polling places, they are surveyed and asked who they voted for in a local election. The campaign team for "Candidate A" wants to know if there is evidence that more than half of all voters voted for their candidate. If there is evidence that their candidate won the majority of the votes, they will order balloons and cake for their big celebration party later that evening.

E. If you were working with this campaign team, what alpha level would you use? Explain your reasoning. [10 points]
