Answer
# Brief Explanations:
1. Mark surveys people on his track - team to determine the exercise habits of all students in his school. Track - team members are more likely to have regular exercise habits compared to the general student population. So, this sample is not representative of all students and is biased.
2. Kaitlyn surveys 100 random people in the hallway to determine how many students plan to attend the school musical. Since the sample is randomly selected from the student population in the hallway, it has a better chance of representing the entire student body's intentions regarding the musical. So, this sample is unbiased.
# Answer:
1. Biased
