Single adults: According to a Pew Research Center analysis of census data, in 2012, 20% of American adults ages 25 and older had never been married. If we repeatedly obtain random samples of 100 adults, what will be the mean of the sampling distribution of sample proportions

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 and standard deviation

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

This means that

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

my answer is$ 12

step-by-step explanation:

because 15 -2=12

this is answer of 144 cubic meters
