The 2010 American Census reported that 72.5% of American adults have not completed a Bachelor's degree (nor do they hold a higher degree). Allowing p = 0.725 to represent the population proportion of American adults who have not completed a Bachelor's degree, we can collect random samples of 40 American adults. Describe the sampling distribution of .
| A. |
The sampling distribution is approximately normal with a mean of 0.725 and a standard deviation of 0.0706. |
|
| B. |
None of the answers is correct. |
|
| C. |
The sampling distribution is approximately normal with a mean of 0.725 and a standard deviation of 0.0998. |
|
| D. |
The sampling distribution is approximately normal with a mean of 40 and a standard deviation of 6.31. |
