2. You find a line of fit for a set of data and calculate that the correlation coefficient for the model is -0.34. Which statement best describes the fit of the model to the data?
A. The correlation coefficient suggests a strong positive correlation, so this model is a good fit for the data.
B. The correlation coefficient suggests a weak positive correlation, so this model is a not a good fit for the data.
C. The correlation coefficient suggests a weak negative correlation, so this model is a not a good fit for the data.
D. The correlation coefficient suggests a strong negative correlation, so this model is a good fit for the data.
