answer the following question below

**Quiz Scores Analysis**

**Problem Statement:**
The following are all 6 quiz scores of a student in a statistics course. Each quiz was graded on a 10-point scale:
```
8, 9, 5, 10, 9, 7
```

Assuming that these scores constitute an entire population, find the standard deviation of the population. Round your answer to *two decimal places*.

**Instructions for Calculating Standard Deviation:**

1. **Find the Mean (Average):**
   Add all the scores together and divide by the number of scores.
   
   Mean \( \mu \) = \( \frac{8 + 9 + 5 + 10 + 9 + 7}{6} \)

2. **Calculate Each Score's Deviation from the Mean:**
   Subtract the mean from each score to get the deviation for each score.
   
3. **Square Each Deviation:**
   Square each of the deviations.

4. **Find the Mean of These Squared Deviations:**
   Add up all the squared deviations and divide by the number of scores.

5. **Take the Square Root of This Mean:**
   The square root of this value is the population standard deviation.
