Answer 1

The design flaw in this survey is undercoverage bias.

Explanation:

The survey question is about public support for funding community college education. The sample comprises entirely of 1,000 people on campus. So, the result of the survey will be biased towards public support for funding community college education. It is undercoverage bias because the vast majority of the publc not on campus are not included in the sample.
