I rounded 9.27 repeating to 9.28 to make it easier to solve. It would be 232/25 as an improper fraction and 9 and 7/25 as a mixed number.
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
<span>Expressed as a mixed number, 13/5 is equal to 2 3/5 or two and three fifths.
Hope this helps.</span>
