The Rosenberg self-esteem questionnaire is a 10-item scale, using a 4-point Likert scale format in each item ranging from strongly agree to strongly disagree, measures global self-worth by measuring both positive and negative feelings about the self. Higher scores indicate higher self-esteem. Suppose a study is done to six adolescents to determine if self-esteem (Y) depends on the height (X; in inches). Results are shown below.

 Height (inches) Self-esteem 58 28 60 30 63 31 67 33 69 34 70 37   The scatterplot is shown on the left.   What is the linear regression model that shows the relationship of height and self-esteem?
