Dr. Cоttа is interested in the cаuses оf behаviоral problems among children. To study this, she employs the “Behavioral Tendencies” scale, which uses parents’ and teachers’ ratings to score children on a scale of 1-70. (Higher scores indicate more behavioral problems.) The population mean on this scale is 29.87. Dr. Cotta suspects that one of the many causes of behavioral problems is a stressful home environment. She gathers a random sample of 61 children who have been classified as living in a stressful home. For this sample the mean score on the Behavioral Tendencies scale is 36.95.
