exam by having a sample of students at a particular school take the exam. The
quality of the students at the chosen school varies widely and the school
administrators are allowed to choose who sits the exam. The administrators
have a strong incentive for the school to do well on the exam. Do you think the

any, do you think will be present? Briefly explain.

sample proportion, what conditions must be met?
