A politician claims that 55% of the voters in her district will vote for her in an upcoming election. A poll of 680 random voters in that district indicates that 340 would vote for her. Use this data to calculate the appropriate test statistic to test her claim at the 1% significance level.
Do not round intermediate calculations. Enter your answer as a decimal rounded to two places. Indicate a negative value with a "–" sign directly before the value.

1.) Voting records show that 61% of eligible voters actually did vote in a recent presidential election. In a survey of 1002 people, 70% said that they voted in that election. Use the survey results to test the claim that the percentage of all voters who say that they voted is equal to 61%. Test the claim by constructing an appropriate confidence interval. What are the null and alternative hypotheses? What is the value of = significance level? Is the...

Judging on the basis of experience, a politician claims that 46% of voters in a certain area have voted for an independent candidate in past elections. Suppose you surveyed 25 randomly selected people in that area, and 17 of them reported having voted for an independent candidate. The null hypothesis is that the overall proportion of voters in the area that have voted for an independent candidate is 46%. What value of the test statistic should you report? The test...

An exit poll at an election of 1000 voters shows that 540 voted for Homer Simpson. Of course, Homer is guaranteed to win the election if more than half of the population voted for him (or the population proportion p> 0.5). Can Homer claim victory at the 0.05 level of significance? What is the p-value of the test statistic? (9 points)

Given the sample data below, test the claim that the proportion of male voters who plan to vote Republican at the next presidential election is more than the percentage of female voters who plan to vote Republican. Use the P-value method of hypothesis testing and use a significance level of 0.10. Based on the result, can we say that Republicans resonate better with male voters than with female voters? Men: n1 = 250, x1 = 146 Women: n2 = 202,...
