Hyperactivity in children is usually treated by counseling, drugs, or both. An experiment was conducted to evaluate efficacy of counseling/no counseling and drug/no drug on attention span (time spent concentrating on a task) in 124 children diagnosed with attention deficit hyperactive disorder (assume random assignment and equal n per group). 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 xdrug = [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.
