I need help with the plotting and this question.

Compute r. (Round your answer to three decimal places.)

**Determining the Weight of a Healthy Shetland Pony: An Investigation**

**Introduction**

Understanding the weight of a healthy Shetland pony at various ages helps in monitoring their growth and ensuring their well-being. Here, we examine the relationship between the age of the pony (in months) and its average weight (in kilograms).

**Dataset**

Consider the following dataset:
- \( x \): age of the pony in months
- \( y \): average weight of the pony in kilograms

| \( x \) | 3 | 6 | 12 | 14 | 23 |
|--------|---|---|----|----|----|
| \( y \) | 60 | 95 | 140 | 168 | 173 |

**Objective**

(a) Create a scatter diagram of the data and determine the best-fit line.

**Scatter Diagram Instructions**

1. **Graphing Tool Interface:** 
   - On the left side of the graphing tool interface, various tools are available for plotting and modifying graph elements.

2. **Plotting Points:**
   - Plot the data points corresponding to the age and weight pairs:
     - (3, 60)
     - (6, 95)
     - (12, 140)
     - (14, 168)
     - (23, 173)

3. **Best-Fit Line:**
   - After plotting the points, draw a line that best represents the trend of the data. This line should minimize the distance between itself and all the data points (i.e., the least squares method).

**Graph Explanation**

- **X-Axis (Horizontal Axis):** Represents the age of the pony in months.
- **Y-Axis (Vertical Axis):** Represents the average weight of the pony in kilograms.
- **Scatter Points:** Display individual data points given in the dataset.
- **Graph Layers Panel:** Allows for the adjustment and management of graph properties, ensuring clarity and precision in data representation.

**Conclusion**

Creating a scatter diagram helps visualize the growth trend of Shetland ponies over time. A best-fit line provides a generalized model to predict the weight of a pony at any given age within the observed range. This graphical approach is essential for veterinary care, breeding programs, and ensuring the overall health of Shetland ponies.
