A researcher wants to understand the average height of all high school students in a large city. They measure the height of every tenth student entering the school cafeteria at one high school. Is this sample likely to be representative of the population of all high school students in the city? Explain why or why not. A company wants to gauge employee satisfaction. They send out a survey to all employees but only receive responses from those who volunteer to participate. Is this sample of responses likely to be representative of the entire employee population? Explain why or why not. A news organization wants to determine the public's opinion on a new local policy. They conduct interviews with people at a popular downtown park on a Saturday afternoon.
