Mrs. Stroberg wants to make sure every student passes Biology. She thinks that if she
pays some students that they will study more for tests and quizzes and get higher
scores. So she decides to pay half the students $20 a week to put in more time to study
for any test or quiz. After a month, she looks at all the test and quiz scores and notices
that the average score on every test and quiz are the same in both groups.
