Recently, several long-time customers at the Sweet Haven Chocolate Company have complained about the quality of the chocolates. It seems there are several partially covered chocolates being found in boxes. The defective chocolates should have been caught when the boxes were packed. The manager is wondering which of the three packers is not doing the job properly. Clerk 1 packs 40% of the boxes and usually has a 2% defective rate. Clerk 2 packs 30%, with a 2.5% defective rate. Clerk 3 boxes 30% of the chocolates, and her defective rate is 1.5%. Which clerk is most likely responsible for the boxes that raised the complaints?
