Answer 1

Explanation:

(a) Mrs. Bogard is herself a math teacher, so her asking her math class to indicate their favorite subject introduces a strong bias. Some students would try to please Mrs. Bogard by choosing math over history.

(b) If Mrs. Bogard wanted truly unbiased input, she'd have to take the class to another room in which neither math nor history is taught and ask a fellow teacher to do the sampling for her.
