**Problem Statement:**

A random sample of 480 Oklahoma parents with school-aged children showed that 276 had children doing at least some virtual learning. Find a 97.8% confidence interval for the proportion of all Oklahoma parents who have children doing some form of virtual learning.

**Notes:**

- Sample size (\( n \)) = 480
- Number of parents with children in virtual learning = 276
- Confidence level = 97.8%

**Calculation Details:**

- Proportion (\( \hat{p} \)) = \( \frac{276}{480} = 0.575 \)
- Confidence interval = 97.8%
