An environmental action group is interested in how many people will participate in a recycling program in a particular town. They obtain the entire list of households in the town, and they assign each household a number from 1 to 3,000 (the number of households in the town). They then use a computer to generate a list of 500 random numbers ranging from 1 to 3,000. Using the list of random numbers, they draw a sample of 500 people to question their use of the recycling program. What sampling method did this group use? Group of answer choices quota sample simple random systematic stratified random
