Answer 4, 5 and 6

**Calculating P-Values for Various Scenarios**

Determine the p-value for each of the following scenarios. Ensure your answers are rounded to four decimal places.

1) **Right-tailed test**
   - Test statistic value: \( t = -2.94 \)
   - Degrees of freedom: \( df = 8 \)
   - P-value: [ ] 

2) **Right-tailed test**
   - Test statistic value: \( t = 1.01 \)
   - Degrees of freedom: \( df = 5 \)
   - P-value: [ ] 

3) **Left-tailed test**
   - Test statistic value: \( t = -0.8 \)
   - Degrees of freedom: \( df = 17 \)
   - P-value: [ ]

4) **Left-tailed test**
   - Test statistic value: \( t = 2.06 \)
   - Degrees of freedom: \( df = 20 \)
   - P-value: [ ]

5) **Two-sided test**
   - Test statistic value: \( t = 2.26 \)
   - Degrees of freedom: \( df = 13 \)
   - P-value: [ ]

6) **Two-sided test**
   - Test statistic value: \( t = -0.99 \)
   - Degrees of freedom: \( df = 22 \)
   - P-value: [ ]
