Answer:
Approximately Normal, with a mean of 950 and a standard error of 158.11
Step-by-step explanation:
To solve this question, we need to understand the Central Limit Theorem.
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, a large sample size can be approximated to a normal distribution with mean and standard deviation, which is also called standard error 
.
In this problem, we have that:
The sampling distribution of the sample mean amount of money in a savings account is
By the Central Limit Theorem, approximately normal with mean 
and standard error 
So the correct answer is:
Approximately Normal, with a mean of 950 and a standard error of 158.11
