#### Precision and Margin of Error

- In the example, we saw the 95% confidence interval is (0.499,\ 0.901), which is quite big, and therefore is not very useful. There are measures to describe situations like these too.

- The distance between the sample estimate and the endpoints of the confidence interval is called the margin of error (M). For a 95% confidence interval,
