Question

miss mason wanted to pick a movie for her students to watch on friday fun day, so she put a list of potential movies next to the classroom door. of all her students, 3 decided to vote. is this a random sample of the teachers students? yes no

Explanation:

A random sample requires that every member of the population (here, all the teacher's students) has an equal chance of being selected. In this case, only students who decided to vote (voluntary response) were included, not every student had an equal chance (e.g., students who didn't notice the list, didn't care to vote, etc., were excluded). So it's not a random sample.

Answer:

no
