Part 4 (30 points) Scenario: Special Agent David Rossi has become tired of field work and putting his life at risk, so he decides to understand the minds of criminals through research from the safety of his new university office. His current research investigates the role of parenting style on violent behavior in patients with schizophrenia. To test this, he goes to local hospitals to recruit people with schizophrenia for his study. Specifically, he contacts the parents of each patient and asks questions to determine if their parenting style was Authoritative, Permissive, or Uninvolved. He contacts the parents of patients until he has 5 patients in each parenting style condition. Then, he gives the doctors at the hospitals an adapted Aggression Questionnaire (AGQ) which is designed to measure violent behavior in their patients. The AGQ is on a scale of 29 (low) to 203 (extremely high) Below are the data USE THE SPACE BELOW TO SHOW YOUR WORK. YOU MUST SHOW ALL WORK IN ORDER TO RECEIVE CREDIT.
