Question

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 stratified random sample of guests based on the venues zones. which of these strategies will accomplish their intended design? choose 1 answer: a randomly select 50 tickets from each zone and invite those guests to participate in the survey. b invite the first 150 guests that arrive to participate in the survey. c randomly select a row, and invite every guest in that row to participate in the survey. continue to randomly select rows like this until about 150 total guests have been selected. d invite every 10th guest who arrives to participate in the survey until 150 people have been selected. e use a computer to randomly select 150 tickets and invite those guests to participate in the survey.

Explanation:

Stratified random sampling divides the population into subgroups (strata) and then samples from each stratum. Here, the strata are the three ticket - zones. Option A divides the sample of 150 guests evenly among the three zones by randomly selecting 50 from each zone, which is stratified random sampling. Option B is a convenience sample as it just takes the first 150 guests. Option C is cluster sampling as it selects entire rows (clusters). Option D is systematic sampling as it selects every 10th guest. Option E is simple random sampling as it randomly selects 150 tickets without considering the zones.

Answer:

A. Randomly select 50 tickets from each zone and invite those guests to participate in the survey.
