Answer
Brief Explanations:
A simple random sample is when each element has an equal chance of being selected without a fixed pattern. A systematic sample selects elements at regular intervals. A stratified sample divides the population into subgroups and samples from each subgroup. A cluster sample divides the population into clusters and samples entire clusters. Here, testing every 200th cell - phone is at a fixed interval, which is characteristic of a systematic sample.
