A researcher measures a person's mood and how creative he or she is (higher scores indicate more positive mood and more creativity), obtaining the following interval scores: Participant 1 2 3 4 5 6 7 Mood Score (X) 10 9 9 6 2 7 3 Creativity Score (Y) 9 7 5 8 5 6 4 The Pearson correlation coefficient between mood and creativity is +0.62. a) b) c) d) e) What is the regression equation in this example? What is the predicted creativity score for anyone scoring a 2 on mood? What is the predicted creativity score for anyone scoring a 8 on mood? What is the average error in your predictions (i.e., SY')? What is the proportion of variance accounted for in this example
