Answer:
20.27
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean and standard deviation
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean
and standard deviation
Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?
This is s when . So
So the correct answer is:
20.27
