Ten individuals have participated in a diet-modification program to stimulate weight loss. Their weights both before and after participation in the program is shown in the following list. Is there evidence to support the claim that this particular diet-modification program is effective in producing mean weight reduction? Compare the weight before to the weight after the diet modification program.
