Assistant:  address your requests for questions 31-40 regarding Janice and Paul's study on stress and life satisfaction, we'll need to work through the correlation calculation first. Given the following data:

| Participant | Stress Score | Life Satisfaction Score |
|-------------|--------------|-------------------------|
| 1           | 11           | 10                      |
| 2           | 25           | 22                      |
| 3           | 23           | 25                      |
| 4           | 11           | 30                      |
| 5           | 22           | 11                      |
| 6           | 25           | 30                      |
| 7           | 30           | 10                      |

### Calculation of Correlation Coefficient (r)

To calculate the correlation coefficient (r), you can use the formula:

\[ r = \frac{n(\sum xy) - (\sum x)(\sum y)}{\sqrt{[n \sum x^2 - (\sum x)^2][n \sum y^2 - (\sum y)^2]}} \]

Where:  
- \( n \) = number of pairs  
- \( x \) = stress scores  
- \( y \) = life satisfaction scores  
- \( \sum xy \) = sum of the product of paired scores  
- \( \sum x \) = sum of stress scores  
- \( \sum y \) = sum of life satisfaction scores  
- \( \sum x^2 \) = sum of squares of stress scores  
- \( \sum y^2 \) = sum of squares of life satisfaction scores  

### Using Slovin's Formula for Sample Size Calculation

Slovin's Formula is used to calculate the sample size required for a study:

\[ n = \frac{N}{1 + N \times e^2} \]

Where:  
- \( N \) = number of target population  
- \( n \) = sample size required  
- \( e \) = margin of error (expressed as a decimal)  

For both margin of errors (10% and 5%):

1. **For a 10% margin of error (e = 0.10):**  
   \[ n = \frac{10,000}{1 + 10,000 \times (0.10)^2} = \frac{10,000}{1 + 100} = \frac{10,000}{101} \approx 99.01 \]  
   *Thus, the required sample size is approximately 99.*

2. **For a 5% margin of error (e = 0.05):**  
   \[ n = \frac{10,000}{1 + 10,000 \times (0.05)^2} = \frac{10,000}{1 + 25} = \frac{10,000}{26} \approx 384.615 \]  
   *Thus, the required sample size is approximately 385.*

### Summary Results
- The correlation coefficient can be computed by plugging in the values discussed above.
- For a population of approximately 10,000, the required sample size is about 99 for a 10% margin of error and 385 for a 5% margin of error.
