In the year 2018, 23% state citizens who voted in person had to wait in line for more than two hours. The state government is unhappy about this and decides to implement a more streamlinedvoting scheme in 2020. They are hoping that, with the new voting scheme, a reduced percentage of the in-person voters end up waiting in line for more than two hours in 2020.In a random sample collected by the end of 2020, 17 of 80 in-person voters in the state actually waited in line for more than 2 hours. We will conduct a hypothesis test to see whether the newvoting scheme is effective.First, determine which of the following pairs of hypotheses is appropriate.(1) H, : p = 0.23 vs. HA : p < 0.23(2) Ho : p = 0.2125 vs. HA : p < 0.2125(3) Ho : p = 0.23 vs. HA : p < 0.23(4) Ho : p = 0.2125 vs. HA : p < 0.2125(5) Но : р— 0.23 vs. HA : р— 0.2125O a.

Exit polling is a popular technique used to determine the outcome of an election prior to results being tallied. Suppose a referendum to increase funding for education is on the ballot in a large town (voting population over 100,000). An exit poll of 500 voters finds that 245 voted for the referendum. How likely are the results of your sample if the population proportion of voters in the town in favor of the referendum is 0.51? Based on your result, comment on the dangers of using exit polling to call elections. Question content area bottom Part 1 How likely are the results of your sample if the population proportion of voters in the town in favor of the referendum is 0.51?
Suppose a researcher from the School of Education at SU wanted to know whether or not students at SU preferred taking classes online or in person this coming Fall 2020 semester. The researcher plans to collect a sample by preparing an optional online survey sent out via e-mail in which students are asked to circle preferences ”online,” ”in person,” or ”not sure.” There is also comment box in the survey where students can express their opinions and concerns. This method of sampling is an example of which of the following: (i) convenience sampling (ii) voluntary response sampling (iii) stratified random sample (iv) multi-stage sampling
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.

In recent years, many states have enacted tougher voter identification laws requiring a government issued photo ID. Proponents claim that these laws are necessary to reduce voter fraud. Opponents claim that voter fraud is rare and that since as many as 11% of eligible voters do not have the required identification, these tougher laws will discourage millions of minorities and low-income Americans from voting. The Washington Post conducted a national poll (July 7-19, 2012) and found that 1558 out of 2064 adults supported the tougher voter ID laws. 1)Construct a 95% confidence interval for the proportion of adults who approve of tougher voter ID laws. Document your work in the space provided below. Document how you computed the margin of error and the confidence interval in the space provided below. Round all numbers to 4 decimal places. 2)Is it likely that three-fourths of adults approve of these new laws?
Exit polling is a popular technique used to determine the outcome of an election prior to results being tallied. Suppose a referendum to increase funding for education is on the ballot in a large town (voting population over 100,000). An exit poll of 300 voters finds that 147 voted for the referendum. How likely are the results of your sample if the population proportion of voters in the town in favor of the referendum is 0.51? Based on your result, comment on the dangers of using exit polling to call elections.
