Critical Thinking: What does the survey tell us? Surveys have become an integral part of our lives. Because it is so important that every citizen has the ability to interpret survey results, surveys are the focus of this project. The Pew Research Center recently conducted a survey of 1007 U.S. adults and found that 85% of those surveyed know what Twitter is.

Analyzing the Data

Assume that you are a newspaper reporter. Write a description of the survey results for your newspaper.

A survey consisted of 1007 U.S. adults. 85% of those who were surveyed know what Twitter is.

Referring to Exercise 7-1FDD, the 95% confidence interval estimate of the percentage of adults, who know what Twitter is, is equal to (82.8%, 87.2%).

Based on the above interval, the following statements can be used as a report for the newspaper describing the results of the survey:

“According to the results of the survey, it can be said that there is 95% confidence that the percentage of adults who know what Twitter is lies between 82.8% and 87.2%. Upon observing the results, a significant proportion of people are familiar with the social media platform. Only about 12 to 17% of the people are not familiar with Twitter.”
