Refer to the Pew Internet and American Life Project (April 2008) survey of the writing habits of U. S. teenagers. 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 the rate of all U. S. teenagers have used at least one informal element in school writing assignments differs from 65%? Test the relevant hypotheses using alpha 0 .05. What is the hypothesis?
