A psychologist wishes to determine which of four diet plans works best. The psychologist randomly assigns 32 overweight clients to one of four diet plans: Life on Herbs (LOH), E-mail-A-Meal (EAM), Weight-Lookers (WLK), and Low-Carbs (LOC). The numbers represent weight loss in pounds for 3 months for each client.$\begin{array} { c c c c }
\hline \text { LOH } & \text { EAM } & \text { WLK } & \text { LOC } \
