(b) Does there appear to be a relationship between x and y? If so, how do you describe it? A. Yes, there appears to be a positive relationship between x and y. As x increases, y increases. B. Yes, there appears to be a negative relationship between x and y. As x increases, y decreases. C. No, there is no relationship between x and y. (c) Calculate the correlation coefficient, r. (Round your answer to two decimal places.) r = Does the value of r confirm your conclusions in part (b)? Explain. Yes, the value of r indicates a strong negative relationship between x and y. Yes, the value of r indicates no relationship between x and y. Yes, the value of r indicates a strong positive relationship between x and y. No, the value of r indicates no relationship between x and y. No, the value of r indicates a strong negative relationship between x and y.
