Answer:

The mean of the sampling distribution of sample proportions will be 0.2

Step-by-step explanation:

Central Limit Theorem for Proportions:

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean \mu = p and standard deviation s = \sqrt{\frac{p(1-p)}{n}}

20% of American adults ages 25 and older had never been married.

This means that p = 0.2

So the mean of the sampling distribution of sample proportions will be 0.2
