A researcher investigates the effectiveness of an experimental weight-loss program. Sixteen volunteers will participate, half assigned to the experimental program and half placed in a control group. In a study such as this, it would be good if the average weights of the subjects in the two groups were approximately equal at the start of the experiment. Here are the weights, in pounds, for the 16 subjects before the study begins. 168 210 182 238 198 175 205 215 186 178 185 191 221 226 188 184 First, use a matching procedure as the method to form the two groups (experimental and control), and then calculate the average weight per group. Second, assign participants to the groups again, this time using random assignment (use an online random generator such as random.org). Again, calculate the average weight per group after the random assignment has occurred. Provide the average weights for the matching and random procedures. Are the average weights for the groups closer to each other with matching or with random assignment? In
