A political scientist claims that 38% of first-year college students characterize themselves as being “moderate” or “middle of the road” as far as their political affiliation is concerned. Believing this claimed value is too high, you survey a random sample of 400 first-year college students and find that 120 characterize themselves as being “moderate” or “middle of the road.” Based on this information, what will the test statistic be? Choose the answer below that is closest to what you calculate, and try not to do a lot of rounding until you get to the very end of your calculations. 1. -0.3 2. -1.2 3. -2.6 4. -3.3 5. None of the other answer options are correct because the test statistic should be positive, not negative.
A political researcher takes a survey of 310 randomly selected registered voters in Orlando, and each person was asked who they plan on voting for in the 2024 presidential election. 110 said they plan on voting for Candidate A, 185 said they plan on voting for Candidate B, and 15 were unsure or plan to vote for another candidate. The researcher wants to construct a 95% confidence interval for the proportion of all registered voters in Orlando who plan to vote for Candidate B. What is the point estimate? Round final answer to 3 decimal places.
A random sample of 1,000 voters was drawn and asked on a bipartisan basis about their voting intentions ahead of the recent animal federal election.

Refer to the data set of 2020 randomly selected presidents given below. Treat the data as a sample and find the proportion of presidents who were taller than their opponents. Use that result to construct a 95% confidence interval estimate of the population percentage. Based on the result, does it appear that greater height is an advantage for presidential candidates? Why or why not? PRESIDENT HEIGHT HEIGHT OPP Jackson 185 171 Polk 173 185 Taft 182 178 Johnson 192 180 Pierce 178 196 J. Kennedy 183 182 Garfield 183 187 F.

Find the percentage of voters who chose Candidate A. % (Round to one decimal place as needed.) b. Is it appropriate to find a confidence interval for the proportion of voters who chose Candidate A? O A. No, it is not appropriate to find a confidence interval because the conditions for the Central Limit Theorem are met. B. No, it is not appropriate to find a confidence interval because the proportion is a population proportion. C. No, it is not appropriate to find a confidence interval because there are three possible outcomes for each observation. D.
