Transcribed Image Text:### Understanding Bivariate Data and Regression Analysis
**Bivariate Data Table:**
The table presents quantitative variables \( x \) and \( y \):
| \( x \) | \( y \) |
|---------|---------|
| 5.8 | 6.7 |
| 7.4 | 8.3 |
| 3.1 | 1.8 |
| 4.6 | 4.0 |
| 3.0 | 0.8 |
| 5.9 | 6.6 |
| 4.9 | 3.7 |
| 6.7 | 7.3 |
| 6.7 | 4.8 |
| 3.4 | 2.7 |
| 7.8 | 8.1 |
| 7.0 | 5.9 |
| 3.6 | 1.8 |
| 3.9 | 3.7 |
| 5.7 | 4.8 |
| 8.3 | 9.7 |
| 9.0 | 9.8 |
| 8.0 | 8.3 |
**Scatter Plot:**
- The scatter plot visualizes the relationship between the \( x \) and \( y \) values.
- Each point represents a data pair from the table.
- The \( x \)-axis ranges from 1 to 11, while the \( y \)-axis ranges from 0 to 11.
- A general upward trend is observed in the data points, indicating a positive correlation between \( x \) and \( y \).
**Least-Squares Regression Line:**
- The graph prompts sketching an approximate least-squares regression line.
- This line minimizes the sum of the squared differences between observed values and the values predicted by the line.
- The icon next to the graph suggests tools for drawing or interacting with the plot.
For a more detailed study, analyze the scatter plot to assess the strength and direction of the linear relationship, which aids in understanding how variable \( y \) changes with \( x \).
