Abel Bates · Answer 1

Step-by-step explanation:

We have to recall the central limit theorem for statistic distributions.

The central limit theorem states that as sample sizes grow large and samples are drawn at random from the population, the sample mean will follow a normal distribution with mean = mean of all sample means.

Thus here we are given 4 choices.

We find that

A distribution of a single statistic from repeated random samples of the same size, from the same population

is the right answer.

Because when we test mean or any single statistic from repeated samples from the same population, we get the normal curve.
