sleet_krkn [62]

Answer:

The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.

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

3% of books borrowed from a library in a year are downloaded.

This means that $p = 0.03$

SRS of 75 books.

This means that $n = 75$

What are the mean and standard deviation of the sampling distribution of the proportion of downloaded books

By the Central Limit Theorem

Mean: $\mu = p = 0.03$

Standard deviation: $s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.03*0.97}{75}} = 0.0197$

The mean of the sampling distribution of the proportion of downloaded books is 0.03 and the standard deviation is 0.0197.
