C. 4

D. 6

E. 8

F. 10

G. 12

3. Why are there two degrees of freedom for the ANOVA conducted and what do they refer to? 4. Report the p-value for the ANOVA conducted. 5. Given the p-value for the ANOVA conducted, what can you conclude about reaction time among these groups?

A. Reject the null hypothesis, there is no difference in mean reaction time among groups

B. Reject the null hypothesis, there is a significant difference in mean reaction time among groups. C. Fail to reject the null hypothesis, there is no difference in mean reaction time among groups

D. Fail to reject the null hypothesis, there is a significant difference in mean reaction time among groups. 6. Briefly explain why the ANOVA results conducted produce different results despite having the same dataset. How do the calculations of their F-ratios differ?
