Question

In 2003, the state of California conducted its first recall election. Over one hundred candidates vied to replace Gray Davis as Governor, with actor Arnold Schwarzenegger winning 49% of the votes cast. In the days before the election, newspapers had published accusations of inappropriate treatment of women by Schwarzenegger, so some suspected that his support from women would be weaker than his support from men. Before the polls closed, pundits tried to predict the election results by using "exit polls," asking people as they left the voting booth who they voted for. In one such poll that year, CNN interviewed 2023 men and 2191 women. A total of 991 men and 942 women said they voted for Arnold. The research question being investigated in this study is whether there is convincing evidence that male voters in 2003 were more likely to say they voted for Arnold than female voters in 2003. 1. Complete the two-way table by giving values to each letter. Male Female Total Voted for AS 991 942 A Did not vote for AS B C D Total 2023 2191 E Please use this template in your answer: A = B = C = D = E = 2. Report the statistic (show 2 decimals) and use the appropriate symbols to represent the statistic. Show your work. TIP: Use the difference in sample proportions as the statistic (NOT the relative risk) 3. State the null and alternative hypotheses in symbols. Use the order MALE – FEMALE.
