Both samples are biased.D
Neither sample is biased.Sample 1 surveyed students at sports practice, so it leaves out students who do not participate in sports and may not represent the whole school. That makes Sample 1 biased. Sample 2 surveyed every fifth student entering the cafeteria, where all students eat, so it is more representative of the student body. The correct choice is “Sample 1 is biased.”
