    Question

    In a sample of 100 individuals, a multiple regression model with two predictors and the interaction between predictors is estimated. The b of the interaction term is 0.75, the se is 0.50.

    Test for significant interaction.


    1. FALSE: t(df=96)=1.50,0.05<p<0.10t(df = 96) = 1.50,\;0.05 < p < 0.10. Interaction is not significant.
    2. TRUE: t(df=96)=1.50,0.10<p<0.20t(df = 96) = 1.50,\;0.10 < p < 0.20. Interaction is not significant.
    3. FALSE: t(df=96)=2.25,0.02<p<0.05t(df = 96) = 2.25,\;0.02 < p < 0.05. Interaction is significant.
    4. FALSE: t(df=96)=2.25,0.01<p<0.025t(df = 96) = 2.25,\;0.01 < p < 0.025. Interaction is significant.
