In a population of 19,100 subjects, 59% possess a certain characteristic. In a sample of 320 subjects selected from this population, 30% possess the same characteristic. How many subjects in the population and sample, respectively, possess this characteristic?
#### Population and Sample Calculation
1. **Population Calculation:**
- Given: Total Population = 19,100 subjects
- Percentage with Characteristic = 59%
- Calculation: \( 19,100 \times 0.59 = 11,269 \)
Therefore, **11,269 subjects in the population** possess the characteristic.
2. **Sample Calculation:**
- Given: Sample Size = 320 subjects
- Percentage with Characteristic = 30%
- Calculation: \( 320 \times 0.30 = 96 \)
Therefore, **96 subjects in the sample** possess the characteristic.
#### Interactive Boxes Explanation:
- The interactive boxes are provided for students to input their answers. Each box has an informational icon (ℹ) that offers additional hints or explanations for better understanding.
- The first box corresponds to the number of subjects in the population who possess the characteristic.
- The second box corresponds to the number of subjects in the sample who possess the characteristic.
