Question: An automobile assembly line operates for two shifts a day. The first shift accounts for two-thirds of the overall production. The task of quality control engineers is to monitor the number of nonconformances per car. Each day a simple random sample of 6 cars from the first shift, and a simple random sample of 3 cars from the second shift is taken, and the number of nonconformances per car is recorded. Does this sampling scheme produce a simple random sample of size 9 from the day's production? Justify your answer.
