![### Estimating the Correlation Coefficient
**Question:** Estimate the correlation coefficient for the data plotted below.
Below is a scatter plot displaying a set of points, each defined by x and y coordinates:
- **X-axis (Horizontal):** Ranges from 0 to 60.
- **Y-axis (Vertical):** Ranges from 0 to 45.
The plotted data points appear to be somewhat scattered, with a general upward trend, suggesting a positive correlation. However, there is one data point around (10, 40) that appears to be an outlier compared to the rest of the data points.
**Options for the correlation coefficient estimate:**
- ○ 0.95
- ○ 0.35
- ○ -0.35
- ○ -0.95
Based on the upward trend and scatter of the data points, select the most appropriate correlation coefficient.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F23f14c8c-5141-4be2-aa93-07a6356450c6%2Fcd3a7323-5760-427f-b0af-f6827281522b%2Fqnzq1kk_processed.jpeg&w=3840&q=75)
