According to the ICR Research Group, 63% of Americans in the 18–34 age group say they are comfortable filing income tax returns electronically, compared to just 49% of those who are 55–64. Using the 0.025 level of significance, and assuming there were 200 persons surveyed from each age group, examine whether Americans in the 18–34 age group might be more comfortable with electronic filing than their counterparts in the 55–64 group. Determine and interpret the p-value for the test.

In an October 2003 poll conducted by the Gallup organization, 684 of 1006 randomly selected adults aged 18 or older stated they think the government should make partial birth abortions illegal, except in cases necessary to save the mother. obtain a point estimate for the proportion of adults 18 and older who think the government should make partial birth abortions legal, except in cases necessary to save the mother.
According to the February 2008 Federal Trade Commission report on consumerfraud and identity theft, 23% of all complaints in 2007 were for identity theft. Inthat year, Arkansas had 1,601 complaints of identity theft out of 3,482 consumercomplaints ("Consumer fraud and," 2008). Does this data provide enoughevidence to show that Arkansas had a higher proportion of identity theft than23%? Test at the 5% level.
A 2015 New York Times/CBS News poll sampled 523 adults who were planning a vacation during the next six months and found that 141 were expecting to travel by airplane. A similar survey question in a May 2005 New York Times/CBS News poll found that of 477 adults who were planning a vacation in the next six months, 81 were expecting to travel by airplane. Let 2015 be population 1. State the hypotheses that can be used to determine whether a significant change occurred in the population proportion planning to travel by airplane over the 10-year period. Let 0.01 be the level of significance. Use α=0.01 and test for a significant difference. What is the value of the test statistic?
The Los Angeles City Controller's office calculated that in 2013, the city employed 4703047030 full‑time employees and 1014210142 part‑time employees. Assume that an outside advocacy group had been lobbying the Mayor's office to convert part‑time workers into full‑time workers throughout 2014. The Controller's office makes its calculations annually. Suppose that the outside advocacy group wanted to know the proportion of city employees (excluding per‑event employees) who are full‑time employees ?p in June 2014 to gauge if their lobbying efforts had been effective. Suppose that the group surveyed a random sample of 1000 city employees (excluding per‑event employees) in June 2014 and found that 845845 were full‑time employees and 155155 were part‑time employees. If the advocacy group planned to use a one‑sample z-z-test for a proportion to test their lobbying eforts, the appropriate null hypothesis would be and the appropriate alternative hypothesis would be Assume…
In a survey of 1,000 women aged 22 to 35 who work full time, 555 indicated that they would be willing to give up some personal time in order to make more money. The sample was selected in a way that was designed to produce a sample that was representative of women in the targeted age group. (a) Do the sample data provide convincing evidence that the majority of women aged 22 to 35 who work full-time would be willing to give up some personal time for more money? Test the relevant hypotheses using ? = 0.01. Find the test statistic and P-value. (Round your test statistic to two decimal places and your P-value to four decimal places.) z = P-value = (B ) State your conclusion. a. Fail to reject H0. We have convincing evidence that a majority of women aged 22 to 35 who work full time would be willing to give up some personal time for more money. b. Fail to reject H0.

In an attempt to document the percentage of teenagers in the United States who play video games for more than 4 hours per day, the group Concerned Citizens for Teenage Welfare surveyed 2,000 teenagers randomly selected from across the United States. It was discovered that 33% of teenagers surveyed play video games for more than 4 hours per day. Concerned Citizens for Teenage Welfare released a statement saying: "If you are the parent of the 33% of teenagers in America who play video games for more than 4 hours per day, you should consider engaging your teen in at least one other activity per day." What does the Concerned Citizens for Teenage Welfare statement represent? a It represents the random sample. b It represents the population parameter. c It represents the sample statistic. d It represents an inference about teenagers in the United States.

A nonprofit company concerned with the school dropout rates has designed a tutoring program aimed at students between 16 to 18 years old. A national center for educational statistics reported that the high school dropout rate for the year 2000 was 10.9%.One school district, who adopted the use of the nonprofit's tutoring program and whose dropout rate has always been very close to the national average, reported in 2004 that 158 of their 1769 students dropped out. Is their experience evidence that the tutoring program has been effective? Determine the hypotheses for this test. Choose the correct answer below A. H0: p=0.109 HA: p≠0.109 B.
