Of the different childhood psychopathologies that exist, one of the most diagnosed of these is Attention Deficit Hyperactivity Disorder (ADHD). Many of these children will require a behavioral management program to teach new, more adaptive behaviors. A very common instrument used to make the diagnosis of ADHD is the Conners Behavior Rating Scales, which has a mean of 45 and a standard deviation of 5. A social worker is interested in knowing whether a new behavioral management program lowers scores on this scale for children diagnosed with ADHD. She takes a random sample of 25 children and finds their mean to be 44.01, with an estimated standard deviation of 3.79. Test the null hypothesis at the .01 level of significance.
