Mikayla designed a survey to determine the number of people expected at opening night of a community theater. The community has about 5,000 members. She selected a sample of the first 25 parents dropping off actors during theater rehearsal. Which best explains Mikayla’s sample?

Mikayla chose the first 25 parents who arrived, rather than selecting people randomly from the community, so the sample is nonrandom. It is also biased because parents dropping off actors may be more connected to the theater and more likely to attend opening night than typical community members. Therefore, the sample is nonrandom and biased.
