Reseаrch results suggest thаt children with ADHD tend tо wаtch mоre TV than children whо 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 a journal recording how much time each day is spent watching TV. The average 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 µ = 4.1 hours per day; the population standard deviation is unknown. Are the data sufficient to conclude that the time spent watching TV is significantly different for children with ADHD than for children without the disorder? Which test should be computed to answer the question?
