![**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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F2f91f0ec-e8b8-45b8-8365-57dfac5940bc%2F135c6b70-8d5b-4148-b59d-5d241ca3ba04%2Fkzp9zot_processed.png&w=3840&q=75)
