Question

**Sample Data Analysis**

This section focuses on analyzing a given sample with the following tasks:

### Sample Details:
The sample consists of the following $ N $ scores: 1, 9, 8, 5, 7.

### Task A:
1. **Calculate the $ \sum X^2 $**: Determine the sum of the squares of each score in the sample.
2. **Calculate the $ \sum X $**: Determine the sum of the scores in the sample.

### Task B:
- **Find the z-score for each score in the sample**: The z-score indicates how many standard deviations an element is from the mean.

### Table Layout:
The table provides a structure for organizing calculations:

| $ X $ | $ X^2 $ | $ z $ |
|---------|-----------|----------|
| 1 | | |
| 9 | | |
| 8 | | |
| 5 | | |
| 7 | | |

Fill in each column by performing the relevant calculations. The $ X^2 $ column should contain the square of each $ X $ value, and the $ z $ column should contain the z-score calculations for each score.
