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 zz-test for a proportion to test the newspaper’s claim?     The random sample condition is not met. A The sample is more than 10% of the population. B The observed number of teens in the sample who do not use social media is less than 10. C The expected number of teens in the sample who do not use social media is less than 10. D The distribution of the population is not approximately normal.
