A. Yes, because the absolute value of the correlation coefficient is less than the critical value.

B. Yes, because the absolute value of the correlation coefficient is greater than the critical value

C. No, because the absolute value of the correlation coefficient is less than the critical value

D. No, because the absolute value of the correlation coefficient is greater than the critical value.
