Beatriz takes a simple random sample of 350350350 orders from the more than 500050005000 total orders to her store and finds that 12\%12%12, percent of the sampled orders were returned. Assuming that it is really 9\%9%9, percent of all orders to her store which were returned, what is the approximate probability that more than 12\%12%12, percent of the sampled orders would have been returned?
