Answer to Question 1

Many people may refuse to talk to a telephone interviewer. If the people who don't answer the phone differ from people who do in whether they plan to watch the next Super Bowl, non-response bias may result. Also, women are more likely to answer the phone and they may be less likely to watch the Super Bowl.

Answer to Question 2

The people who did not vote may be reluctant to admit that they didn't vote, resulting in a response bias.
