![### Survey Analysis
A magazine conducted a poll of 500 adults to identify their favorite pie. Among the 500 respondents, 14% chose chocolate pie. The margin of error is reported as ± 3 percentage points. This document provides guidance on identifying the statistical values mentioned in the survey analysis.
1. **Value of \( \hat{p} \):**
- \( \hat{p} \) represents the sample proportion. In this survey, \( \hat{p} \) is 0.14 (or 14%).
2. **Value of \( q \):**
- \( q \) is found by evaluating \( 1 - \hat{p} \). Therefore, \( q = 1 - 0.14 = 0.86 \).
3. **Value of \( n \):**
- \( n \) is the sample size, which is 500 in this survey.
4. **Value of \( E \):**
- \( E \) is the margin of error, given as ± 3 percentage points.
5. **Value of \( p \):**
- \( p \) represents the population proportion, which needs to be estimated from the sample proportion \( \hat{p} \).
### Confidence Level Calculation
If the confidence level is 99%, what is the value of \( \alpha \)?
- The confidence level of 99% corresponds to a confidence coefficient of 0.99.
- The value of \( \alpha \) is calculated as \( 1 - \text{confidence level} \), so \( \alpha = 1 - 0.99 = 0.01 \).
