Use the following to answer the questions below:

In a survey conducted by the Gallup organization, 1,017 adults were asked, "In general, how much trust and confidence do you have in the mass media — such as newspapers, TV, and radio — when it comes to reporting the news fully, accurately, and fairly?" 81 said that they had a "great deal" of confidence, 325 said they had a "fair amount" of confidence, 397 said they had "not very much" confidence, and 214 said they had "no confidence at all."


Suppose you wish to use the percentiles of your bootstrap distribution to provide a 95% confidence interval for the proportion of U.S. adults who have no confidence in the media.  Which percentiles would you use?

▸ The 10%- and 90%-tiles.

▸ The 1%- and 99%-tiles.

▸ The 5%- and 95%-tiles.

▸ The 2.5%- and 97.5%-tiles.
