In a study of children with a particular disorder, parents were
asked to rate their child on a variety of items related to how well
their child performs different tasks. One item was "Has difficulty
organizing work," rated on a five-point scale of 0 to 4 with 0
corresponding to "not at all" and 4 corresponding to "very much."
The mean rating for 289 boys with the disorder was reported as 2.35
with a standard deviation of 1.11. (Round your answers to four
decimal places.)
Compute the 90% confidence interval.
(_______, _______)
