Calculate the sample correlation coefficient rxy. (Round final answer to 4 decimal places.) Sample correlation coefficient a-2. Interpret rxy. The correlation coefficient indicates a positive linear relationship. The correlation coefficient indicates a negative linear relationship. The correlation coefficient indicates no linear relationship. b. Specify the competing hypotheses in order to determine whether the population correlation coefficient between the size of a house and property taxes differs from zero.
