Advice columnist Ann Landers once asked her readers with children to answer the following question: "If you had it to do over again, would you have children?" Readers were invited to send a response to this question by mail. Of the approximately 10,000 responses Landers received, approximately 70% said "no." The sample:
A)is probably representative of all parents.
B)is probably not representative of all parents, because people who feel very strongly about this issue are more likely to respond than people who do not.
C)has little bias, because more than 10,000 people responded, yielding a very large sample.
D)is probably not representative, because more than 10,000 people responded.

The sample is likely to be biased because people who feel strongly about the issue are more likely to respond, leading to an overrepresentation of the "no" response. Additionally, the sample size being more than 10,000 does not necessarily guarantee representativeness, as the key factor is whether the sample is a random and unbiased selection of the population of interest.
