1. Gun safety has been a controversial issue in this country. Suppose a city measure (call it Measure A), banning gun sales to previously convicted criminals, people on a terrorist watch list, and the mentally ill, will be voted on in the next election.

In each scenario, identify the type of bias(es) present. Explain your choice(s).

1. Some members of a group that supports gun rights randomly select 100 people from the county and call them on the phone. Their script says: "The U.S. Constitution guarantees all of its citizens to bear arms. Do you support Measure A that bans gun sales to some citizens?"

1. A TV news station in the city conducts a "text-in" survey. Viewers are asked whether they favor or oppose Measure A and are given instructions on how to send a text message to record their votes. The poll is publicized and responses are solicited by announcements on the TV station's evening news programs.
