4(4a) = 16a

4(20b) = 80b

16a + 80b is your actual answer

About 78% of the US, population claims that they visit the dentist at least once a year. simple random sample of 200 people is s

Blababa [14]

Answer:

D) 0.78, 0.029

Step-by-step explanation:

Central Limit Theorem:

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 $s = \sqrt{\frac{p(1-p)}{n}}$

About 78% of the US, population claims that they visit the dentist at least once a year.

This means that $p = 0.78$

Random sample of 200 people:

This means that $n = 200$

Mean and standard deviation of the sampling distribution:

By the Central Limit Theorem

Mean $\mu = 0.78$

Standard deviation $s = \sqrt{\frac{0.78*0.22}{200}} = 0.029$

So the correct answer is given by option D.
