Dr. Scone administered a "pop quiz" to her honors class of five students and scored it "right minus wrong," which means a negative score was possible. She scored the quizzes, calculated, and recorded the class mean on the exam, m = 5. Dr. Scone, being a bit of a flake, discovered she couldn't find the quiz paper of her favorite student, Padraic, and did not have a score recorded for his quiz. Fortunately, she did have the scores written down for the other four students. They were: 5, 7, 7, and, 8. Show how Ó(X - µ) = 0.
What will be an ideal response?
Correct Answer:
Ó(X - µ) = 0 + 2 + 2 + 3 - 7 = 0
