A concert venue offers tickets in 3 zones: orchestra, grand tier, and balcony. Tickets in the orchestra zone are most expensive, and tickets in the balcony zone are least expensive. Managers of the venue want to survey approximately 150 guests at an upcoming concert about their overall experience. They want to take a systematic random sample of the 3000 guests they expect to attend. Which of these strategies will accomplish their intended design? A. Use a computer to randomly select 150 tickets and invite those guests to participate in the survey
B. Randomly select one of the first 20 guests to arrive and every 20th guest thereafter to take the survey
C. Invite the first 150 guests that arrive to participate in the survey
D. Randomly select 50 tickets from each zone and invite those guests to participate in the survey
