each law firm in one state registers its phone number with the state court system. an employee of the state court system uses a computer to select 500 random registered phone numbers, and the law firms associated with those numbers will be selected for an audit. what type of sample is this? choose 1 answer: a simple random sample b stratified random sample c cluster random sample d systematic random sample
Answer
# Brief Explanations:
In a simple - random sample, every member of the population has an equal chance of being selected. Here, the state court system employee uses a computer to randomly select 500 registered phone numbers from all registered phone numbers of law firms. There is no stratification (division into subgroups), no clustering (selection of groups), and no systematic pattern (like selecting every nth element). Each law - firm's phone number has an equal probability of being chosen.
# Answer:
A. Simple random sample
