Final Answer :
C
Explanation :
The sign of the Pearson correlation coefficient indicates the direction of the relationship (positive or negative) and the value of the coefficient indicates the strength of the relationship. Statistical significance can also be determined through hypothesis testing. The range of the coefficient is always between -1 and 1, and linearity is assumed unless otherwise specified.
