### Problem-Solving Exercise: Analyzing Scatter Plots

**Task:**
Use the scatter plots shown, labeled **a** through **f**, to solve the problem.

---

**Scatter Plots Description:**

- **Plot a:**
  - **Axes:** X-axis (1 to 6), Y-axis (2 to 12)
  - **Pattern:** Negative linear trend with dots decreasing from top left to bottom right.

- **Plot b:**
  - **Axes:** X-axis (1 to 7), Y-axis (2 to 12)
  - **Pattern:** Positive linear trend with dots increasing from bottom left to top right.

- **Plot c:**
  - **Axes:** X-axis (1 to 6), Y-axis (2 to 12)
  - **Pattern:** A horizontal spread of dots around the center, showing no obvious trend.

- **Plot d:**
  - **Axes:** X-axis (1 to 6), Y-axis (2 to 12)
  - **Pattern:** Positive linear trend similar to plot **b**, with dots increasing from bottom left to top right.

- **Plot e:**
  - **Axes:** X-axis (1 to 7), Y-axis (2 to 12)
  - **Pattern:** Scattered dots without a strong trend, spread across the plot.

- **Plot f:**
  - **Axes:** X-axis (1 to 6), Y-axis (2 to 12)
  - **Pattern:** Negative linear trend with dots decreasing from top left to bottom right.

**Question:**
In which scatter plot is \( r = 0.01 \)?

- Options:
  - \( \circ \) c
  - \( \circ \) e
  - \( \circ \) f
  - \( \circ \) d

Given the choices, scatter plot **e** exhibits the pattern closest to a correlation coefficient (\( r \)) of 0.01, indicating little to no correlation between the variables.
