Answer: 1976

Steps:

Let t* be the year in which the population reached a count of 8920. Solve for t*:

$P=200t+1720\\8920=200t^*+1720\\7200=200t^*\\t^* = 36$

The population grew to the number 8920 in 36 years past 1940, i.e., 1976

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
