In Terms of Probability Theory,the Standard Error Is Valuable Because

In terms of probability theory,the standard error is valuable because

A) it is an estimate of the parameter.
B) it is an estimate of the statistic.
C) it indicates the extent to which the sample estimates will be distributed around the population parameter.
D) it indicates the extent to which the sample estimates will be distributed around the population parameter and thereby gives us an estimate of the parameter.
E) it indicates the extent to which the sample estimates will be distributed around the population parameter and thereby gives us an estimate of the statistic.
