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.
3)We see that the width of the interval increases with confidence level.

Dylan has built a simple clinometer by attaching a weighted string to the center of a protractor. he then attached a straw to the protractor to use as a sight. by looking at an object through the straw, dylan can determine the angle of elevation to that object. 1. dylan is using his clinometer to him determine the height of a tree. he stands 6m from the base of the tree and takes the measurement shown on the clinometer. then, he measures the height of his eye to be 1.6m above the ground a. sketch a diagram to represent this scenario.
