If a random sample of size $n$ is drawn from a normal population, then the sampling distribution of the sample mean $\bar{X}$ will be:
A. approximately normal for all values of $n$
B. approximately normal only for $n > 30$
C. normal for all values of $n$
D. normal only for $n > 30$

The standard deviation of the sampling distribution of the sample mean is also called the:
A. standard error of the mean
B. population standard deviation
C. central limit theorem
D. finite population correction factor
