Question 318050: resent results suggest that children with ADHD also tend to watch more tv than children who are not diagnosed with the disorder. to examine this relationship, a researcher obtains a random sample of n=36 children, 8 to 12 years old, who have been diagnosed with ADHD. Each child is asked to keep ajournal recording how much time each day 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 mu=4.1 hours with a standard deviation = 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 twst with alpha level = .05

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 level = .05

Ho: u(AD)-u(gen) = 0
Ha: u(AD)-u(gen) > 0

I was planning to run a two sample T test
but you did not list the std for the AD
group.
