The correlation coefficient measures the strength and direction of a relationship between two variables. It ranges from -1 to 1, with values closer to -1 or 1 indicating a stronger relationship, and values closer to 0 indicating a weaker relationship. Since the variables are not specified, we cannot determine the exact value of the correlation coefficient, but we know that it is positive and greater than 0.34 since 320,000/340 is greater than 940. Therefore, the best choice is C, 0.60, which is the closest value to the lower bound of our estimated range.
