![**Exercise: Calculating Z-Score**
The NAEP geography assessment scores for eighth-grade students are approximately normally distributed with a mean of 257 and a standard deviation of 35.
**Task:**
Find the z-score for a score of 252. Please round your answer to two decimal places.
**Solution Area:**
⎕ (placeholder for the answer)
**Instructions:**
To find the z-score, use the formula:
\[ z = \frac{(X - \mu)}{\sigma} \]
Where:
- \( X \) is the value for which you are finding the z-score (252 in this case),
- \( \mu \) is the mean (257),
- \( \sigma \) is the standard deviation (35).
Substitute the values and calculate the z-score.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F6f0561ea-00fb-4c75-a2e9-c26d09539570%2F9fca270d-cc6a-4103-a0fc-9ecccb1ce970%2Ftzr1qj_processed.jpeg&w=3840&q=75)
