scenario
Nora would like to conduct an experiment to determine whether behavior modification techniques can help children eliminate bedwetting. She obtains a sample of children who wet the bed and randomly assigns half to the behavior modification therapy and half to a control group who receive no therapy. After six months, she measures how often children in each group wet the bed.
-Suppose Nora obtains the following printout of information:

\begin{array} { | l l l l | } \hline \text { GROUP } & N & M & S D \\\text { Therapy } & 10 & 1.60 & 1.07 \\\text { Control } & 10 & 5.50 & 0.85 \\t = - 9.00 & & d f = 18 & p = .001 \\\hline\end{array}

What decision should Nora make?
A) The results are significant; children treated with behavioral modification therapy wet the bed less often than children in the control group.
B) The results are not significant; children treated with behavioral modification therapy wet the bed less often than children in the control group.
C) The results are significant; children treated with behavioral modification therapy and children in the control group did not differ in terms of bedwetting.
D) The results are not significant; children treated with behavioral modification therapy and children in the control group did not differ in terms of bedwetting.
