**Educational Content: Analyzing the Relationship Between Two Variables** In this exercise, we aim to assess the relationship between two variables: students' midterm and final exam scores. The data is presented in a tabular format to facilitate analysis. ### Data Table: | Student | Midterm (x) | Finals (y) | x² | y² | xy | |---------|-------------|------------|------|------|------| | 1 | 75 | 80 | 5625 | 6400 | 6000 | | 2 | 70 | 75 | 4900 | 5625 | 5250 | | 3 | 65 | 65 | 4225 | 4225 | 4225 | | 4 | 90 | 95 | 8100 | 9025 | 8550 | | 5 | 85 | 80 | 7225 | 8100 | 7650 | | 6 | 85 | 85 | 7225 | 7225 | 7225 | | 7 | 90 | 90 | 8100 | 8100 | 8100 | | 8 | 75 | 70 | 5625 | 4900 | 5250 | | 9 | 95 | 90 | 9025 | 8100 | 8550 | ### Summary Values: - Σx = 775 - Σy = 815 - Σx² = 60925 - Σy² = 67325 - Σxy = 64000 #### Analysis Steps: 1. **Appropriate Statistical Test:** - Identify the statistical test that will help analyze the relationship between midterm and final scores. 2. **Computing the Correlation Coefficient (r):** - Formula: The correlation coefficient, denoted as 'r', is calculated to quantify the strength and direction of the relationship between the two variables. - Space provided for the computed r value: ___________ 3. **Conclusion/Interpretation:** - Analyze the resultant 'r' value based on the following criteria: - If 0 < r < 0.25, there's a weak correlation. - If 0.25 ≤ r <
