<PRE><B>Question 318050</B>
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 test with alpha level = .05
----
Ho: u(AD)-u(gen) = 0
Ha: u(AD)-u(gen) &gt; 0

----
I was planning to run a two sample T test 
but you did not list the std for the AD 
group.
