Answer:
C.The mean of the sampling distribution is always
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation , a large sample size, of at least 30, can be approximated to a normal distribution with mean and standard deviation .
So
A is wrong, because it is
B is wrong, you need a sample size of at least 30.
So the correct answer is:
C.The mean of the sampling distribution is always
