Question

Quizplus · Accepted Answer

The selection of 30 students using randomizer.org indicates that they were chosen randomly from the larger population of 135 students in the statistics class. Therefore, they represent a simple random sample of the class. A census would involve surveying or gathering data from every single member of the population, which is not the case here. A voluntary response sample would involve individuals choosing whether or not they wish to participate in the study, which is not the case here.
