Question
Construct a 95% confidence interval of the population proportion using the given information.

\[ x = 240, \, n = 300 \]

**Table of Critical Values:**

A popup table can be accessed, which provides critical values for different levels of confidence:

- **90% Confidence Level:** 
  - Area in Each Tail: 0.05
  - Critical Value (\( z_{\alpha/2} \)): 1.645
- **95% Confidence Level:** 
  - Area in Each Tail: 0.025
  - Critical Value (\( z_{\alpha/2} \)): 1.96
- **99% Confidence Level:** 
  - Area in Each Tail: 0.005
  - Critical Value (\( z_{\alpha/2} \)): 2.575

**Tasks:**

- The lower bound is \(\_\_\_\_\).
- The upper bound is \(\_\_\_\_\).

*Note: Round to three decimal places as needed.*
