Retain the null hypothesis.
Reject the null hypothesis.
State the decision for the interaction effect.
Retain the null hypothesis.Reject the null hypothesis.
(b) Based on the results you obtained, what is the next step?
Compute simple main effect tests for the significant interaction.
Compute pairwise comparisons for the technology factor.
Compute pairwise comparisons for the length factor.
No further analysis is needed, because none of the effects are significant.
