**Estimating Minimum Sample Size for a 95% Confidence Interval**

To ensure the accuracy of statistical studies, it is essential to determine the minimum sample size needed. This computation is crucial for achieving a specific margin of error at a desired confidence level.

**Problem Statement:**

Estimate the minimum sample size needed to achieve the margin of error \( E = 0.008 \) for a 95% confidence interval.

---

**Solution:**

The minimum sample size is \[ \_\_\_\_ \] (Round up to the nearest integer.)

---

**Explanation:**

When planning a study, understanding the minimum number of observations required helps in designing more reliable and effective experiments and surveys. This is influenced by factors like the confidence level, margin of error, and population variability.

**Note:**

This section might include detailed diagrams or graphs typically used to visually represent how sample sizes affect confidence intervals and margins of error, but there are no specific diagrams included in this transcription.
