The equation for a. is 80=5.50x+45
B is 6 including him
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
O.6 easy because of the answer that is why
