Answer 16

" there favorites will be used" indicates a BIAS. We want data from all users of the cafeteria, not just the teachers.

Please note: you mean "their" here, not "there."

Answer 17

"a box will be placed at the school entrance for parents to drop off there meal suggestions. Every 10th suggestion will be used" No good, because there'd not be any input from students.

Excellent catch mathmale, I didn't read carefully enough.
