Answer:
And we can find the probability using the normal standard distribution table and with the complement rule we got:
Step-by-step explanation:
For this problem we have the following parameters:
We select a sample size of n =100 and we want to find this probability:
The distribution for the sample mean using the central limit theorem would be given by:
And we can solve this problem with the z score formula given by:
And if we find the z score formula we got:
And we can find the probability using the normal standard distribution table and with the complement rule we got:
The answer is: 5% of 500 is 100
