This is а clоsed-bооk test. Mаke sure your cell phone is put аway--do not even look at it during the exam. You may use scratch paper during this exam. Show the front and back of each blank page to your webcam now if you did not do so during the room scan. If you did not do a thorough room scan earlier, including the desktop area where you have your computer, do so right now. Failure to properly complete the room scan may cause you to have to repeat the exam later. And don't forget to do the Exam 3 Bonus assignment after completing this exam (extra credit). Good luck!
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 100 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. She computes the following test statistic: t = 1.66. If Dr. Cotta conducted a one-tailed hypothesis test (α = .05), a) what decision should she make regarding the null hypothesis? b) Then in “plain English” what does this tell her about the effects of a stressful home environment on behavioral problems? Make sure you include the statistics in APA format.
