#### (a) Find the t-value such that the area in the right tail is 0.005 with 7 degrees of freedom.
- **[Round to three decimal places as needed.]**
- [Input box]
#### (b) Find the t-value such that the area in the right tail is 0.025 with 16 degrees of freedom.
- **[Round to three decimal places as needed.]**
- [Input box]
#### (c) Find the t-value such that the area left of the t-value is 0.02 with 22 degrees of freedom. [Hint: Use symmetry.]
- **[Round to three decimal places as needed.]**
- [Input box]
#### (d) Find the critical t-value that corresponds to 90% confidence. Assume 9 degrees of freedom.
- **[Round to three decimal places as needed.]**
- [Input box]
---
### Note:
- Use the t-distribution table to locate the appropriate t-values based on the specified degrees of freedom and the given tail areas.
- Remember to utilize the symmetry of the t-distribution, especially for part (c).
This guide is structured to help you practice finding t-values for hypothesis testing and confidence intervals, enriching your understanding of statistical concepts.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F176956f4-1bee-45e1-bfac-3c560845af15%2Fe6c52cf5-3b25-40e1-bf33-0dfb2d7a38e1%2Fced27o_processed.jpeg&w=3840&q=75)
