Researchers at a weight loss clinic are conducting an experiment to determine whether weighing oneself daily does in fact lead to greater weight loss while on a diet, as is commonly assumed. They plan to compare the percentage of total body weight lost after twelve weeks on the clinic's diet plan for two groups of people,one weighing themselves every dayandone not weighting themselves while on the diet.Eight volunteers that are just beginning the weight loss program are available participate in this study. For each of these volunteers (numbered 1 through 8), the weight loss clinic collected information on the method by which the volunteerheard about the weight loss programandwhether the volunteer us going to exercise while on the diet plan.This information is presented in the table (below). Based upon this information, the researchers have decided to incorporate blocking into their experimental design.

A.Identify (by number) the volunteers that you would group into blocks. Justify your choice of blocks.

B. For the design in (a), describe an appropriate method for assigning treatment (weighing yourself every day or not) to each of the volunteers.
