You have done a two-way analysis of variance with age at birth of first child (AGEKDBRN) as the dependent variable and CLASS and SEX as the factor variables.
A) Is the overall model statistically significant? (yes / no)
B) Is the interaction effect statistically significant? (yes / no / skipped) (If this step was skipped because of earlier conclusions, write the word "skipped" as your answer.)
C) Is the main effect of CLASS statistically significant? (yes / no / skipped) (If this step was skipped because of earlier conclusions, write the word "skipped" as your answer.)
D) Is the main effect of SEX statistically significant? (yes / no / skipped) (If this step was skipped because of earlier conclusions, write the word "skipped" as your answer.)
