A poll found that in a random sample of
1000 American adults, 720 indicated that they oppose the
reinstatement of a military draft. Is there convincing evidence
that the proportion of American adults who oppose reinstatement of
the draft is greater than 0.7? Use a significance level of 0.05.
(Round your test statistic to two decimal places and your P-value
to four decimal places.)

A poll asked the following question: "If
the military draft were reinstated, would you favor or oppose
drafting women as well as men?" 49 percent of the 1000 people
responding said that they would favor drafting women if the draft
were reinstated. Using a 0.05 significance level, carry out a test
to determine if there is convincing evidence that fewer than half
of adult Americans would favor the drafting of women. (For z give
the answer to two decimal places....
In 2001, the Gallup poll found that 81% of American adults believed that there was a conspiracy in the death of President Kennedy. In 2013, the Gallup poll asked 1,039 American adults if they believe there was a conspiracy in the assassination, and found that 634 believe there was a conspiracy ("Gallup news service," 2013). Do the data show that the proportion of Americans who believe in this conspiracy has decreased? Test at the 5% significance level. 1- What is...
25. A 2012 Gallup poll asked a random sample of 120 American adults whether they thought the news media exaggerate the seriousness of global warming. The proportion who responded "No" was 59.2%. Is this good evidence that majority of American adults do not believe the news media exaggerate the seriousness of the global warning? a) Set up appropriate null and alternative hypothesis to answer the above question b) Calculate the value of the test statistic. c) Is the data significant...
In a random sample of 1000 American households, 37 watched the television program Young Sheldon on one particular Thursday. Is there enough evidence at a = 0.05 to support the claim that more than 3% of American households watched this program? Standardized test statistic: (Round to 2 or 3 decimal places.) P-value: (Round to 4 decimal places.) There (type is or is not) enough evidence at the 5% level of significance to support the claim that more than 3% of...
An article states that movie attendance declined in 2005. A survey found that 690 of 1000 randomly selected adult Americans preferred to watch movies at home rather than at a movie theater. Is there convincing evidence that the majority of adult Americans prefer to watch movies at home? Test the relevant hypotheses using a 0.05 significance level. (For z give the answer to two decimal places. For P give the answer to four decimal places.)z = P = The data ---Select---...
A July 2015 Gallup poll interviewed by phone a random sample of 1009 American adults; 675 said they were regular coffee drinkers. Find the numerical value of the statistic ?̂, and then give a 95% confidence interval for the proportion of American adults who are regular coffee drinkers.
In a previous poll, 36% of adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Suppose that, in a more recent poll, 378 of 1108 adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Is there sufficient evidence that the proportion of families with children under the age of 18 who eat dinner together seven nights a week has decreased?...
In a poll of 1013 adults, it was found that 22% smoked cigarettes in the past week. Use a 0.05 significance level to test the claim that less than 25% of adults have smoked within the past week. Use this information to answer the following questions. The null and alternate hypothesis The test statistics is . (Round to two decimal places) The p-value is . (Round to three decimal places)
A 2020 Pew Research poll found that 65% of U.S. adults believe that President Donald Trump was too slow to make major steps to stop the spread of the coronavirus. Let's assume that 0.65 is the population proportion. Suppose random samples of 100 U.S. adults are randomly selected, and the proportion of each sample is found. What is the probability that a random sample of 100 adults have a sample proportion greater than 70%? Round the probability to 2 decimal...
