(Solution) 14 On January 6, just after the National Basketball Association labor dispute was settled, the Gallup Poll asked a random sample of 671 adults


14 On January 6, just after the National Basketball Association labor dispute was settled, the Gallup Poll asked a random sample of 671 adults "How much have you missed watching NBA basketball since the dispute started?" 60% answered "Not at all." Gallup says that the margin of error for this results is plus or minus 4 percentage points. This means that

 

A. We can be 95% confident tht between 56% and 64% of all adults did not miss watching NBA games.

 

B. We can be certain that between 56% and 64% of all adults did not miss watching NBA games.

 

C. In many samples, all the results would fall between 56% and 64%.

 

D. We are 95% confident that if we take one more sample the result will fall between 56% and 64%.

 

 

15 A recent Gallup Poll asked "What is your favorite Summer Olympics event?" Of the people asked, 27% said "swimming." Here is what Gallup says about the accuracy of this poll:

 

The results are based on telephone interviews with a sample of 1,007 national adults, aged 18 years and older, conducted July 25-27, 2008. For results based on the total sample of national adults, one can say with 95% confidence that the maximum error attributable to sampling and other random effects is plus or minus three percentage points. In addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls.

 

In Gallup's statement, "95% confidence" means (assuming there is no bias)

 

A. We know that 95% of all adults would give the same answer that this poll found.

 

B. If Gallup repeated this poll many times, 95% of all the polls would find that 27% of the people interviewed say swimming is their favorite Summer Olympic event.

 

C. This poll is one of the 95% of all Gallup polls that give correct results.

 

D. If Gallup repeated this poll many times, 95% of the results would be within plus or minus three percentage points of the truth about the population.

 

 

16 Which of these is a correct confidence statement based on this Gallup Poll, assuming there is no bias?

 

A. We are 95% confident that between 24% and 30% of all adults would say swimming is their favorite Summer Olympic event.

 

B. We are 95% confident that between 24% and 30% of the 1,007 people interviewed would say swimming is their favorite Summer Olympic event.

 

C. There is a 95% chance that the opinions of the 1,007 people interviewed fairly represent the opinions of all adults.

 

D. In many samples, 95% will find that 27% of the people interviewed would say swimming is their favorite Summer Olympic event.
