Question

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: [ ]
