A Pew Internet and American Life Project (Apr. 2008) survey interviewed 700 randomly selected U.S. teenagers by telephone on their writing habits. Overall, 448 of the teenagers admitted using at least one informal element in school writing assignments. Recall that in a random sample of 700 teenagers, 448 admitted to using at least one informal element in school writing assignments. [Note: Emoticons, such as using the symbol “:)” to represent a smile, and abbreviations, such as writing “LOL” for “laughing out loud,” are considered informal elements.] Is there evidence to indicate that less than 65% of all U.S. teenagers have used at least one informal element in school writing assignments?
