Answer 1

Selma wants to know if seventh grade students prefer to do their math homework in silence or with background music. She polled the 24 students in her music class. Eight students preferred to do their math homework in silence, and sixteen students preferred to do their math homework with background music.

Is there a sampling bias in the situation above?
Yes. Selma is only curious about 7th grade students, but 6th grade students may prefer background music too.
No. Selma picked a completely random sample for her study.
Yes. Students in the music class will probably enjoy listening to music more than other students.
