Surveys tend to suffer from low response rates. Based on past experience, a researcher determines that the typical response rat
e for an e-mail survey is 20%. She wishes to obtain a sample of 200 respondents, so she e-mails the survey to 2000 randomly selected e-mail addresses. Assuming the response rate for her survey is 20%, will the respondents form an unbiased sample? Explain.
According to my research on different sampling problems, I can say that based on the information provided within the question yes it will form an unbiased sample. This is because an unbiased sample refers to the fact that everyone in the population had the same equal chance of being selected. Seeing since she chose 2000 randomly selected addresses then everyone had the same chance of responding and being selected.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
