**Text:**

A survey of 2390 musicians showed that 304 of them are left-handed. Find a point estimate for p, the population proportion of musicians that are left-handed. Round the estimate to the thousandths place.

**Explanation:**

To find the point estimate for \( p \), the population proportion of left-handed musicians, we use the formula:

\[ p = \frac{x}{n} \]

where \( x \) is the number of left-handed musicians (304) and \( n \) is the total number of musicians surveyed (2390).

Calculate \( p \) as follows:

\[ p = \frac{304}{2390} \]

To round this estimate to the thousandths place, compute the division and round accordingly.
