Chapter 12.2, Problem 19E
The Knight Foundation investigated whether high school students agreed with the statement that people should be allowed to burn or deface the American flag as a political statement. This question was asked in a survey of a representative sample of high school students in 2004 and again in a survey of a representative sample of high school students in 2014 (“Future of the First Amendment: 2014 Survey of High School Students and Teachers,” knightfoundation.org/media/uploads/publication_pdfs/Future_of_the_First_Amendment_cx2.

A state highway commission is considering removing the lane that allows people to pay cash for a toll on a toll road and requiring all people who use the toll road to pay with an electronic transponder that is connected to their car. The commission wants to know whether the proportion of people who live in the northern part of the state and are in favor of removing the cash lane is different from the proportion of people who live in the southern part of the state and are in favor of removing the cash lane. Independent random samples are selected from the northern and southern parts of the state. The table summarizes the responses of those surveyed.

In a recent submission to a Joint Select Committee of Parliament, the National Consumers' League said “In reality, cow’s milk especially processed cow’s milk, has been linked to a variety of health problems, including: mucous production, haemoglobin loss, childhood diabetes, heart disease, arteriosclerosis, arthritis, kidney stones, mood swings, depression, irritability, allergies.” Researchers know this to be true, though the Committee rejected the submission. Suppose that 34% of the population has mood swings, allergies, irritability and depression (MAID) and is known to consume dairy products. Also, 80% of the populace consumes dairy products. Suppose a randomly chosen dairy products user is tested, what is the probability this person has MAID?
Select one:
a. 0.425
b. 0.460
c. 0.140
d. 0.272
In a study conducted by Zogby International for the Democrat and Chronicle, more than 700 New Yorkers were polled to determine whether the New York state government works. Respondents surveyed were asked questions involving pay cuts for state legislators, restrictions on lobbyists, term limits for legislators, and whether state citizens should be able to put matters directly on the state ballot for a vote. The results regarding several proposed reforms had broad support, crossing all demographic and political lines.
Suppose that a follow-up survey of 100 individuals who live in the western region of New York was conducted. The party affiliation (Democrat, Independent, Republican) of each individual surveyed was recorded, as well as their responses to the following three questions.
Should legislative pay be cut for every day the state budget is late?
Yes _________ No _________
Should there be more restrictions on lobbyists?
Yes _________ No _________
Should there be term limits…

They were particularly interested in learning if there aregroup differences in whether people viewed voting as a, “Privilege that comes withresponsibilities and can be limited” or a, “Fundamental right for every U.S. citizen and shouldnot be restricted.” They found differences in these perspectives between the two leading politicalparties, with more Democrats reporting that they viewed voting as a fundamental right comparedto Republicans. However, they were also interested in determining if there were differencesbetween different racial/ethnic groups and compared the responses of white, Black, Hispanic,and Asian survey respondents. What statistical test should be used to determine if there are differences between the surveyed racial/ethnic groups? Assume parametric assumptions are met. A.

- A survey of a random sample of U.S. adults by The Pew Research Center for the People and the Press conducted in early January 2010 recorded each participant’s highest level of education completed and whether they knew that responding to the Census was required by law. Of the 973 participants who had some college or less, 271 knew that responding to the Census was required by law. Of the 526 participants who had a college degree or more, 195 knew that responding to the Census was required by law.

- A consulting firm that surveyed consumers’ holiday shopping behavior found that the percentage of consumers from the US, Canada, and China who said that they planned to spend more on holiday shopping were 40%, 34% and 73%, respectively The survey also found that the percentage of consumers from the US, Canada, and China who said that they were willing to share personal information with retailers in order to receive personalized offers from retailers were 55%, 46% and 72%, respectively Assume that there are equal portions of consumers being surveyed from each of the three countries, the survey results are good representations of the three populations of consumers, and whether a consumer plans to spend more on holiday shopping is statistically independent of whether he/she is willing to share personal information with retailers in order to receive personalized offers from retailers If you randomly select a consumer from the US, what is the probability that the consumer plans to…arrow_forwardAccording to the Pew Research Center,on the propotion of the American population who use only a cellular telephone (landline) is 0.37. Jason conducts a survey of one hundred fifty 20 to 24 year olds who live on their own and finds that 73 do not have a landline to their home. Does this provide sufficient evidence to conclude that the proportion of 20 to 24 year olds who live on their own and don't have a landline is greater than 0.37? Use a=0.10 level of significance.

Specifically, Kryptonosis seems to have killed 12 of Kentville’s inhabitants last year. A neighboring community, Lanesburg, has 25,000 inhabitants and is far enough from the smelter to not be affected by the emission. In Lanesburg, only three people last year died of Kryptonosis. Given that the number of deaths in Kentville and their causes last year were: Heart attack=7 Accidents=4 Kryptonosis=12 Other=6 What is the risk of dying of Kryptonosis in Kentville relative to non-contaminated locality?What is the risk of dying of Kryptonosis in Kentville relative to deaths due to other causes?

- Do sit down restaurant franchises and fast food franchises differ significantly in stock price? Specifically, is the average stock price for sit-down restaurants different from the average stock price for fast food restaurants? If sit down restaurants are considered group 1 and fast food restaurants are group 2, what are the hypotheses of this scenario?arrow_forwardAccording to the American Management Association, most U.S. companies now test at least some employees and job applicants for drug use. The U.S. National Institute on Drug Abuse claims that about 15% of people in the 18-25 age bracket use illegal drugs. Allyn Clark, a 21 year-old college graduate, applied for a job at the Acton Paper Company, took a drug test, and was not offered a job. He suspected that he might have failed the drug test, even though he does not use drugs. In checking with the company's personnel department, he found that the drug test has 99% sensitivity, which means that only 1% of drug users incorrectly test negative. Also, the test has 98% specificity, meaning that only 2% of nonusers are incorrectly identified as drug users. Allyn felt relieved by these figures because he believed that they reflected a very reliable test that usually provides good results. But is this really true? The accompanying table shows data for Allyn and 1,499 other job applicants.

Also, 45 percent of the disputes over wages are resolved without strikes, 70 per-cent of the disputes over working conditions are resolved without strikes, and 40 percent of the disputes over fringe issues are resolved without strikes.
