C)b = the slope of the regression line
D)Y = the observed score of the dependent variable

Question

Quizplus · Accepted Answer

- A is correct because X represents the independent variable in the linear regression equation.
- B is correct because a is the Y-intercept, which represents the value of Y when X is equal to 0.
- C is correct because b is the slope of the regression line, which represents the amount by which Y changes for each unit increase in X.
- D is incorrect because Y is not the observed score of the dependent variable in the equation, but rather the predicted score based on the values of a, b, and X.
