1. (4 pts) A nutritionist wants to conduct a study to validate the effectiveness of a certain herb (Mint Leaves) as an aid in weight loss. She has her nurse randomly assign half a group of overweight people to receive the herb with instructions on how to take and a planned diet for six weeks. The other half of the group is given parsley (which they think is the herb) with the same instructions and the same diet. Each participant is assigned a number and the nurse weighs each subject on Friday of each week. Upon completion of the six weeks she gives the nutritionist the weights of each subject by their assigned number.
