Answer to Problem 10E
The sample is a self-selected sample.
The sample is much likely to represent the population.
Yes, surveys are useful tool for gathering information.
Explanation of Solution
Given information:
The given statement is:
“A researcher wants to know the opinions that people in a state have about filling out surveys. The researcher asks the first 30 people who volunteer to take a survey. Do you think surveys are a useful tool for gathering information?”
The population consists of all types of people in the state. Because the people volunteered themselves to take the survey, the sample is a self-selected sample.
The sample is much likely to represent the population because no fixed class of population was chosen and they randomly volunteered for the survey.
Yes, surveys are useful tool for gathering information.
