The interval estimate for two values overlaps.What might this indicate?
A) Both points may actually have the same value in the general population, although one appears slightly higher, possibly due to uncertainty of the sample.
B) The range between the two points absolutely represents a genuine difference in the general population.
C) Both points must be equal if there is any overlap among their interval estimates because of error in estimating the population from a sample.
D) There is no way to tell if the difference between the two points is genuine.

An overlap among the interval estimates indicates that the true values for the two points could be the same in the general population, but due to the uncertainty of using a sample to estimate the population parameters, the estimates appear slightly different in the sample. Therefore, it is possible that there is no true difference between the two points.
