![**Contaminated Water Study: Confidence Interval Calculation**
**Scenario:**
In a sample of 41 water specimens collected from a construction site, 23 were found to contain detectable levels of lead.
**Task:**
Part 1 of 3
(a) Construct a 95% confidence interval for the proportion of water specimens that contain detectable levels of lead. Round your answers to at least three decimal places.
**Answer Format:**
A 95% confidence interval for the proportion of water specimens that contain detectable levels of lead is [ \( \underline{\qquad\text{ lower bound}}\qquad \) < \( p \) < \( \underline{\qquad \text{ upper bound}}\qquad \) ].
**Action:**
Enter your calculations in the designated fields.
