hello??@cz1

Answer 2

D
There is bias because the people selected were at a sporting event, and these people may favor sports more than other people surveyed. Also, since it was taken at a baseball game, most likely the people would choose that baseball is their favorite sport. If it was taken at a football or basketball game for example, people would be biased for those sports. An accurate survey should be random and unbiased.
