![**Title: Calculating a T-Score for a Confidence Interval**
---
**Determine the t-score for a 99% confidence interval for a population mean from a sample of size 8.**
- \( t = \) [Input field]
[Three decimal accuracy]
---
**Explanation:**
To calculate the t-score for a 99% confidence interval when given a sample size of 8, you can use the t-distribution table. Since the sample size is 8, you have 7 degrees of freedom (sample size - 1). Look for the t-value corresponding to 99% confidence level and 7 degrees of freedom. This will typically involve using statistical software or a t-table that provides values for different levels of confidence and degrees of freedom.
**Note:** Ensure to round the t-value to three decimal places for accuracy.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa1e2aa54-477c-466c-8e4c-b132463d41a1%2F607853bd-163d-4784-ba0b-f5655e74934f%2Fu5fz5v_processed.jpeg&w=3840&q=75)
