True or False?

1.In a two-way ANOVA, if null hypothesis for the main effect of the row variable is rejected, then the null hypothesis for the column variable must also be rejected.

2.If the two lines on a line graph of cell means overlap or make any contact at all, then there must be an interaction.

3.The formula for degrees of freedom in the chi-squared test of independence is the same as the formula for degrees of freedom for the interaction in a two-way ANOVA.

4.In a two-way ANOVA, if you fail to reject the null hypothesis for the interaction, then you must also fail to reject the null hypotheses for the main effect of the row and column IVs.

5.The null hypothesis for the interaction in a two-way ANOVA is that there is no interaction.
