Concept explainers
To identify: The sample and the population. Also classify the sample as simple, stratified or systemic.

Answer to Problem 6CYU
Sample: People who receive the questionnaire.
Population: All citizens of the country.
The sample is a simple random sample.
Explanation of Solution
Given:
A nostalgia television network wants to conduct a cartoon marathon. To choose the episodes, they mail a questionnaire to people selected at random throughout the country.
Here, the sample is all people who receive the questionnaire all citizens of the country form the population. Since, the people selected to fill the questionnaire are selected at a random and any other group of people were equally likely to be chosen, the sample is a simple random sample.
