There are different types of interval estimates.
Given a rounded value for some measure, the interval estimate, based on rounding, is the interval from the minimum value that would be rounded up to the given value to the maximum value that would be rounded down to the given value.
For example, given 4.5 with rounding to the tenths, the minimum of the interval is 4.45 and the maximum is 4.55 so that the interval estimate is (4.45, 4.55).
Statistical interval estimates for a random variable (RV) are probabilistic. For example, given some probability measure (for example 95% or 5% significance level), the interval estimate for a random variable is any interval such that the probability of the true value being inside that interval is 95%. Often the interval is symmetrical about the mean value of the RV that is being estimated, but this need not be the case - particularly if the RV is near an extreme of the distribution.

Will you find the number 89 in the interval 79-89?
Yes, if it is the closed interval. No, if it is the open interval.
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.

How do you find the interval for a set of data?
You find the the smallest and largest values. The interval is the largest minus the smallest.
How do you find an interval on a graph?
to find an interval you have to subtract the first two number from each other for example 5 10 15 20 the interval for this set of data is 5
How do you use the word interval in a sentence?
The interval between the wars was often brief, usually simply a period of rearmament. The interval between a lightning flash and the sound of thunder can provide an estimate of a storm's distance from the observer.
