Cassandra's Cogs states in its advertisement that 90% of its orders are ready to ship within three working days. A simple random sample of 100 of the 2,500 orders received during the past month are pulled for an audit. The audit shows that 84 of these orders were shipped on time. If Cassandra's Cogs really ships 90% of its orders within three working days, what is the probability that the proportion in the simple random sample of 100 orders is as small as the proportion in the auditors' sample or smaller? Explain why you were able to use the method you used? Explain your results in the context of the problem.
