Question 1193824
**1. Understand the Null Hypotheses**

* **Factor A:** There is no significant main effect of Factor A on the dependent variable.
* **Factor B:** There is no significant main effect of Factor B on the dependent variable.
* **Interaction (A x B):** There is no significant interaction effect between Factor A and Factor B on the dependent variable.

**2. Compare F-statistics to Critical Value**

* **Factor A:** F = 2.77 
* **Factor B:** F = 4.44
* **Interaction (A x B):** F = 1.52
* **Critical Value:** F = 3.35

* **Decision Rule:** Reject the null hypothesis if the calculated F-statistic is greater than the critical value.

**3. Make Decisions**

* **Factor A:** 2.77 < 3.35. **Do not reject the null hypothesis.**
* **Factor B:** 4.44 > 3.35. **Reject the null hypothesis.** 
* **Interaction (A x B):** 1.52 < 3.35. **Do not reject the null hypothesis.**

**Conclusion:**

* **Only the null hypothesis concerning Factor B should be rejected.**

**Therefore, the correct answer is B.** 

This means there is sufficient evidence to suggest that Factor B has a significant main effect on the dependent variable, while the main effect of Factor A and the interaction effect between A and B are not statistically significant at the 0.05 level.
