Answer:n = 100 scores from a population with σ = 20

Step-by-step explanation:The

Central Limit Theoremestabilishes that, for a random variable X, with mean and standard deviation , the sample means with size n can be approximated to a normal distribution with mean and standard deviation, which is also called standard error, ofn = 5 scores from a population with σ = 20n = 5 scores from a population with σ = 80n = 100 scores from a population with σ = 20.

This one is the correct answer.

n = 100 scores from a population with σ = 40.
