Media Disk, Inc. duplicates over a million 3.5” floppy disks each year by copying masters to stacks of blank disks. The company buys its blank stock from two different suppliers, A and B. The manager has decided to check each supplier’s stock by counting the rejected disks in the next run from 5,000 that just arrived from supplier A and 4,500 that just arrived from supplier B. During the run, the disk duplicators rejected 73 of A’s disks and 56 of B’s. State the appropriate hypotheses to test whether the proportions of defective disks from the two suppliers are the same. At a = 0.05, what can Media Disk conclude? This question is due on day 6.
