Compliance wants to check whether merchant categories are coded correctly. Out of 100,000 transactions, we randomly sampled 400 and found 8 miscoded. Their tolerance threshold is 3%. Can you tell them the overall error rate is below 3%?

合规要抽查交易的商户类别有没有打错。全量10万笔交易里，我们随机抽了400笔，发现8笔类别打错了。合规的容忍线是3%。你能直接告诉他们，整体错误率低于3%吗？
