A newspaper article claims that 92 percent of teens use social media. To investigate the claim, a polling organization selected a random sample of 100 teens, and 96 teens in the sample indicated that they use social media. Given the data, why is it not appropriate to use a one-sample z-test for a proportion to test the newspaper's claim?

The newspaper article made a claim which cannot be just supported by testing or taking results from a single population. The newspaper claim represents teens of the entire world. To get appropriate results, the poling should be held in different parts of the world and the results shall than be analyzed. Taking the results from just a single population and drawing such a big conclusion or claim is wrong.
