Please answer number 2. Make sure to show work! Thanks!

### Practice Problems 1. Use Table 4 of the Appendix to find \( t_c \) for a 0.95 confidence level when the sample size is 18. 2. Use Table 4 of the Appendix to find \( t_c \) for a 0.99 confidence level when the sample size is 4. 3. Use Table 4 of the Appendix to find \( t_c \) for a 0.90 confidence level when the sample size is 22. 4. Use Table 4 of the Appendix to find \( t_c \) for a 0.95 confidence level when the sample size is 12. 5. **Statistical Literacy**: Student’s t distributions are symmetric about a value of \( t \). What is that \( t \) value? 6. **Statistical Literacy**: As the degrees of freedom increase, what distribution does the Student’s t distribution become more like?
