Each child is asked to keep a journal recording how much time is spent watching TV. The average daily time for the sample is M=4.9 hours. It is known that the average time for the general population of 8 to 12 year old children is 4.1 hours with alpha = 1.8. are the data sufficient to conclude that children with ADHD watch significantly more TV than children without the disorder. use a two tailed test with alpha = .05. if the researcher had used a sample of n=9 children and obtained the sample mean would the results be sufficient to reject Ho? compute cohens d for this study.
