A study of an association between which ear is used for cell phone calls and whether the subject is left-handed or right-handed began with a survey e-mailed to 5000 people belonging to an otology online group.and 717 surve were returned. (Otology relates to the ear and hearing.) What percentage of the 5000 surveys were returned? Doe response rate appear to be low? In general what is a problem with a very low response rate? Of the 5000 surveys, square % were returned. This response rate square to be low. (Round to the nearest whole number as needed.) What is a problem with a very low response rate? A. It creates a serious potential for getting a biased sample that consists of those with a special interest in the topiC. B. It does not allow for sufficient replication to produce a random sample. C. It creates a serious potential for confounding which creates a serious potential for erroneous conclusions. D. It indicates a lack of blinding which creates a serious potential for getting a biased sample.

Answer

To find the percentage of surveys returned, divide the number of returned surveys (717) by the total number of surveys sent out (5000), then multiply by 100:\[ \frac{717}{5000} \times 100 \approx 14.34\% \]So, approximately 14% of the surveys were returned.Yes, this response rate appears to be low.The problem with a very low response rate is that it creates a serious potential for getting a biased sample that consists of those with a special interest in the topic (option A).
