Linear Regression Slope Interpretation
Which of the following is true about the interpretation of a nonzero slope in a linear regression model as depicted in the scatter plot above?
A
A nonzero slope indicates evidence of an association between the predictor and response, although the steepness of the slope alone does not determine the strength of the relationship.
B
A nonzero slope implies that the predictor variable perfectly determines the response variable with no error.
C
A nonzero slope confirms that 100% of the variation in the response is explained by the predictor.
D
A nonzero slope is of no consequence unless the intercept is also significantly different from zero.
