Answer:
(c) if n is large, then the sampling distribution of the sample mean can be approximated closely by a normal curve.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation
, the sampling distribution of the sample mean, with a large sample size, can be approximated to a normal distribution with mean
and standard deviation
.
This is valid no matter the shape of the population.
So the correct answer is:
(c) if n is large, then the sampling distribution of the sample mean can be approximated closely by a normal curve.
