A school psychologist is interested in determining if children with attention deficit hyperactivity disorder (ADHD) learn better if
English literature is read to them rather than having them read the material alone by themselves. A random sample of 10 sixth
graders with ADHD is selected and divided into two groups of n=9. One of the groups has a story read to them (Listening Group)
and the other reads the story alone by themselves (Reading Group). A test on the story is given after each group has finished
reading or hearing the story. The following scores were obtained with 20 being a perfect score.
Test the following:
Ho: M1=M2
H1: M1#M2
What do you conclude using alpha = 0.05?
