How do you find the height of two people who's average height together is ft in?
Not enough information - or in other words, there are infinitely many solutions.Choose any height for the same person. Let's assume this height is greater than the average. Calculate the difference between this height and the average, then subtract that from the average to get the second person's height.
What is the height of a cylinder with a diameter of 5 inches?
Any height. The size you have has the base about that of a tin of paint. But it could be any height.
What is the height of a triangle with a base of 8m?
Any height that you like!
What happens to the confidence interval as the sample estimate increases?
Assuming that other measures remain the same, as the sample estimate increases both ends of the confidence interval will increase. In effect, the confidence interval will be translated to a higher value without any change in its size.Assuming that other measures remain the same, as the sample estimate increases both ends of the confidence interval will increase.

Why do you use confidence intervals?
Statistical estimates cannot be exact: there is a degree of uncertainty associated with any statistical estimate. A confidence interval is a range such that the estimated value belongs to the confidence interval with the stated probability.
