Question

1. more than 1 million people sent texts in response to a survey question asked on tv, so this survey result is more valid than a survey of a random sample of 200 people.

Explanation:

This statement is incorrect. A large sample size from a self - selected group (people who texted in response to a TV survey) doesn't necessarily make the survey more valid than a smaller random sample. Self - selected samples (like those who text in) are often biased as they represent only those who are motivated to respond, while a random sample is designed to be representative of the population. In contrast, a random sample of 200 people, if properly selected, can be more representative of the overall population, and thus its results can be more valid for making inferences about the population, even with a smaller sample size.

Answer:

The statement is false. A self - selected sample of over 1 million people (from those who texted in response to a TV survey) is likely biased, while a well - selected random sample of 200 people can be more representative of the population and thus its results can be more valid for population inferences.
