A magazine provided results from a poll of 500 adults who were asked to identify their favorite pie. Among the 500 respondents, 14% chose chocolate pie, and the margin of error was given as ±3 percentage points. What values do \( p \), \( q \), \( n \), \( E \), and \( p̂ \) represent? If the confidence level is 99%, what is the value of \( α \)?

- The value of \( p̂ \) is [dropdown].
- The value of \( q \) is [dropdown].
- The value of \( n \) is [dropdown].
- The value of \( E \) is [dropdown].
- The value of \( p \) is [dropdown].

If the confidence level is 99%, what is the value of \( α \)?

\( α = \) [input box] (Type an integer or a decimal. Do not round.)

\[ \square \] [ ] Type an integer or a decimal. Do not round.

(Note: This explanation is tailored assuming a dropdown for values selection and an input box for calculating α.)

### 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 \( \alpha = 1 - 0.99 = 0.01 \).

This information helps interpret the results and understand the statistical parameters used in estimating public preferences.
