Question 885079
(a) A simple random sample should be a good method to select the people to take the survey.



(b) With a simple random sample, you eliminate most bias that could result in the survey. If you didn't do things randomly, then you may select people who strongly favor the campus and leave out a lot of people who don't like the campus. This would then falsely give you the idea that everyone (on average) likes the campus. To fix this bias, you'd just randomly pick people and that would give you a better snapshot of the population.
