2 Ann Landers who wrote a daily advice column appearing in newspapers across the country once asked her readers If you had it to do over again would you have children Of the more than 10 000 readers who responded 70 said no I m certain your parents would say yes What does this show A The survey is meaningless because of voluntary response bias B No meaningful conclusion is possible without knowing something more about the characteristics of her readers C The survey would have been more meaningful if she had picked a random sample of the 10 000 readers who responded D The survey would have been meaningful if she had used a control group E This was a legitimate sample drawn from her readers and of sufficient size to allow the conclusion that most of her readers who are parents would have second thoughts about having children
