Answer
# Brief Explanations:
1. When the school board asks citizens to call a certain number to express their opinions, those who choose to call are self - selecting. This is a voluntary response sample. Voluntary response samples tend to be biased as people with stronger opinions are more likely to call.
2. The cook asking only the students in Ms. Andrew's first - period class is using a convenience sample. The cook is choosing the sample based on ease of access rather than a random or representative method, which leads to bias.
# Answer:
1. B. The sample is biased because it is a voluntary response sample.
