Answer: Yes, the ones who responded are significantly different from the ones who did not respond and it could have skewed the results of the survey as well.

Explanation:

In survey sampling exists something called Non-response bias, occurs when people selected to complete a survey are unable to do it. In some cases, they are too busy, unwilling, or just don't like completing surveys. Indeed, Nonresponse bias usually occurs when the ones who responded are different in many ways from nonrespondents. With a response rate around 10%, the results are not trustworthy, skewing too much the information obtained in the collected surveys.
