1. Stress -0.040265
Coping 0.047629
Therefore Coping had the strongest relationship with GPA?

2.
H0: the hierarchical model does not significantly improve prediction
H1: the hierarchical model significantly improves prediction
Based on the p-value, Pr(>F) = 1.042e-07 < 0.05. Reject H0. Conclude that no, the hierarchical model does not significantly improve prediction

3. Stress p-value, Pr(>F) = 0.0762 which is close to 1. This suggests that Stress predicts passing well
Coping p-value, Pr(>F) = 0.0013 which is close to 0. This suggests that Coping does not predict passing well, but predicts failing well

4. I think coping is a statistically significant mediator

5. Yes. social support moderated the effect of stress on GPA. The p-values also suggest this

6. Yes, linear regression assumptions were met based on the VIF values under the multicollinearity assumption
