### Poll Results and Analysis

**Overview:**
A newspaper provided a "snapshot" illustrating poll results from 1910 professionals who interview job applicants. The illustration showed that 26% of respondents indicated the biggest interview turnoff is when an applicant has not made an effort to learn about the job or the company. The margin of error for this poll was stated as ±3 percentage points. 

**Question:**
What important feature of the poll was omitted?

**Options:**
1. The confidence interval
2. The confidence level
3. The point estimate
4. The sample size

### Key Components:

- **Poll Results:** 26% of professionals identify lack of applicant preparedness as the top turnoff during interviews.
- **Sample Size:** 1910 professionals.
- **Margin of Error:** ±3 percentage points.
  
### Discussion:

Understanding poll results requires knowledge of several statistical terms:
- **Confidence Interval:** The range within which the true population parameter is expected to fall.
- **Confidence Level:** The probability that the confidence interval contains the true population parameter.
- **Point Estimate:** A single value estimate of a population parameter.
- **Sample Size:** The number of respondents or observations included in the poll or study.

What is missing from this provided information is the **confidence level**. This detail is crucial as it indicates the degree of certainty in the margin of error.

**Choose the Correct Answer:**
- The confidence interval
- **The confidence level** (Correct Answer)
- The point estimate
- The sample size
