Mrs. Schultz, a math teacher, lets her students retake quizzes. Based on past retakes, she has come up with a regression line that uses a student's original score to predict his or her new score with a retake: y = 0.8x + 4.3 Mrs. Schultz's class recently got the results of their first quiz, and five students decided to retake it. These are the results: Original score 24457 New score 6 7 8 8 10 Based on the data, calculate and plot the residuals.
