### Explanation
This table presents the results from an ANOVA test that evaluates the effects of several independent variables on the dependent variable "rincom2".
- **Corrected Model**: This row aggregates the overall effects of the model. The significant F-value (.000) suggests a statistically significant model.
- **Intercept**: This row represents the constant in the model, which is highly significant with a p-value of .000.
- **hrs2**: This variable has a significant effect on the dependent variable with F=23.712, p=.000.
- **sex**: This variable also significantly affects the dependent variable with F=17.976, p=.000.
- **degree**: Across multiple levels (df=4), this variable significantly influences the dependent variable, F=23.296, p=.000.

Step 1: Part 1
From the given ANOVA table it is evident that the p-value (Sig.) for the interaction effect (sex*degree) is 0.237 which is less than 0.05 (significance level). Therefore, the null hypothesis of no interaction effect is not rejected. We can conclude that the factor interaction is not significant.
