Answer: 0.3

## Explanation The Spearman rank correlation coefficient measures the strength and direction of the monotonic relationship between two variables using their ranked values. **Key characteristics of Spearman correlation:** - Ranges from -1 to +1 - +1 indicates perfect positive monotonic relationship - -1 indicates perfect negative monotonic relationship - 0 indicates no monotonic relationship - Based on ranks rather than raw values - Less sensitive to outliers than Pearson correlation **Interpretation of values:** - 0.7 to 1.0: Strong positive correlation - 0.3 to 0.7: Moderate positive correlation - 0 to 0.3: Weak positive correlation - -0.3 to 0: Weak negative correlation - -0.7 to -0.3: Moderate negative correlation - -1.0 to -0.7: Strong negative correlation Since the question doesn't provide the actual data to calculate the coefficient, and given the options range from -0.7 to 0.7, option C (0.3) represents a moderate positive correlation between the stock returns of X and Y.
