Bullying,” according to noted expert Dan Olweus, “poisons the educational environment and affects the learning of every child.” Suppose you are interested in the emotional well-being not only of the victims but also of bystanders, bullies, and those who bully but who are also victims (bully-victims). You decide to measure anxiety in a group of bullies and a group of bully-victims using an 18-item, 5-point anxiety scale. The group of 84 bullies scored an average of 40.1 with a sample standard deviation of 3.8 on the anxiety scale. The group of 67 bully-victims scored an average of 46.8 with a sample standard deviation of 11.6 on the same scale. Suppose you intend to conduct a hypothesis test on the difference in population means. In preparation, you identify the sample of bullies as sample 1 and the sample of bully-victims as sample 2. Organize the provided data by completing the following table:
