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 for284 boys with the disorder was reported as 2.39 with a standard deviation of 1.08. (Round your answers to four decimal places.)
Compute the 90%, 95% and the 99% confiddence interval. (Please show work)
Explain the effect of the confidence level on the width of the interval. (which one is correct?)
1)We see that the width of the interval does not change with confidence level.
2)We see that the width of the interval decreases with confidence level.
