Independent random samples of 100 east-side residents and 120 west-side residents of a large citywere asked whether they will vote for candidate Jones in an upcoming election. Of the 100 east-sideresidents, 70 said they plan to vote for Jones. Of the 120 west-side residents, 72 said they plan tovote for Jones. In the calculation of a 90% confidence interval for the difference in the proportion ofeast-side and the proportion of west-side residents that will vote for candidate Jones, which of thefollowing is the margin of error?(A) 1.28(0.7)(0.3) (0.6)(0.4)100120(B) 1.645 (0.7)(0.3) (0.6)(0.4)100120(C) 1.96+(0.7)(0.3) (0.6)(0.4)100120142 7811(D) 1.645+220 2201001201427811(E) 1.96+220220 100 120

Your local school board wants to determine the proportion of people who plan on voting for the school levy in the upcoming election. They conduct a random phone poll, where they contact 150 individuals and ask them whether or not they plan on voting for the levy. Of these 150 respondents, 78 people say they plan on voting for the levy. The school board wants to determine whether or not the data supports the idea that more than 50% of people plan on voting for the levy. Calculate the p-value for the one-sided Hypothesis test described in this example. (Hint: Find the test statistic and then use the tables to find the p-value.) 0.20 < p-value < 0.30 0.6879 0.3121 greater than 0.5 0.4899
A public opinion pollster wants to estimate the percentage of voters who favor an upcoming proposal. How many voters must be surveyed to construct a 95% confidence interval for the percentage of voters who favor the proposal within 3 percentage points? Remember, sample size must be a whole number.
Among students at a nearby college, the proportion who say they're interested in their congressional district's election results has traditionally been 65%. After a series of gripping debates on campus, a political scientist claims that the proportion, p, of students at the college who say they're interested In their district's election results is now greater than 65%. A poll is commissioned, and 181 out of a random sample of 250 students at the college say they're interested in their district's election results. Is there enough evidence to support the political scientist's cdaim at the 0.10 level of significance? Perform a one-tailed test. Then complete the parts below.

Among students at a nearby college, the proportion who say they’re interested in their congressional district’s election results has traditionally been 70%. After a series of lackluster debates on campus, a political scientist claims that the proportion, p, of students at the college who say they’re interested in their districts election results is now less than 70%. A pill is commissioned, and 154 out of random sample of 230 students at the college say they’re interested in their districts election results. Is there enough evidence to support the political scientist’s claim at the 0.05 level of significance? Perform a one-tailed test. Then complete the parts below. Carry your intermediate computations to three or more decimal places and round your answers as specified in the table.
Construct a 95% confidence interval for p1 - p2 for a survey that finds 30% of 240 males and 41% of 200 females are opposed to the death penalty. Group of answer choices a.(-0.200, -0.021) b.(-1.532, 1.342) c.(-1.324, 1.512) d.(-0.561, 0.651)
A survey asked 827 randomly sampled registered voters in California to select a response best fitting their opinion about drilling for oil and natural gas off the coastline of California. Response options include (1) Support, (2) Oppose, or (3) Do not know enough to answer. Data was disaggregated along whether respondents were college graduates or not. Here's the data: Support Drilling Oppose Drilling Doesn't Know Graduated College 154 180 104 Didn't Graduate College 132 126 131 Does this data show a statistically significant difference in the support of drilling between those who graduated college and those who didn't?
A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only wants a 3% margin of error at a 98% confidence level, what size of sample is needed? The political candidate will need to sample people.
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. A total of 610 people said they would vote for the Cat Party. Calculate the 95% confidence interval for the proportion of voters who intend to vote for the Cat Party. Interpret confidence intervals based on this poll and comment on the chances of the Dog Party returning to power.
One of the questions in a study of marital satisfaction of dual-career couples was to rate the statement, "I'm pleased with the way we divide the responsibilities for childcare." The ratings went from 1 (strongly agree) to 5 (strongly disagree). The table below contains ten of the paired responses for wives and husbands. Conduct a hypothesis test at the 5% level to see if wife's satisfaction levels are lower than their husband's satisfaction level (meaning that, within the partnership, the husband is happier than the wife). Wife's score 3 2 3 3 4 2 1 1 2 4 Husband's score 2 2 1 3 2 1 1 1 2 4 NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) Part (a) State the null hypothesis. H0: ?d = 0 H0: ?d > 0 H0: ?d < 0 H0: ?d ≠ 0 Part (b) State the alternative hypothesis. Ha: ?d > 0 Ha:…
In a recent poll of 1,003 people conducted by Ipsos Ipsos (see: https://projects.fivethirtyeight.com/biden-approval-rating/ ), 53% of the respondents disapproved of President Biden. Find a 95% confidence interval for the proportion of all people who disapprove of President Biden. Find a 99% confidence interval for the proportion of all people who disapprove of President Biden. What are the respective margins of errors in parts a) and b) and why are they different?
