Given SScounseling x drug = 1.2 and SSerror = 5.1, what conclusion can you draw regarding the interaction at an alpha level of .05? dfcounseling x drug = [a] dferror = [b] MScounseling x drug = [c] (2 decimals) MSerror = [d] (2 decimals) critical Fcounseling x drug = [e] (2 decimals) computed Fcounseling x drug = [f] (2 decimals) We [g] (reject/do not reject) the null hypothesis because p [h] (> or < or =) alpha. Thus, we conclude that the interaction [i] (is/is not) significant
