The superintendent of a large school district wants to test the effectiveness of a new program designed to improve reading skill among elementary school children. There are 30 elementary schools in the district. The superintendent chooses a simple rando sample of five schools, and institutes the new reading program in those schools. A total of 4700 children attend these five scho The sample is a (Choose one) v sample. simple random cluster systematic convenience voluntary response stratified
