Tyler Apiaries sells bees and beekeeping supplies. Bees (including a queen) are shipped in special packages according to weight. Suppose Tyler changes its processes so that the average package weight is now 1.5kg, with a new standard deviation of 0.2 kg. Tyler markets the packages of bees as weighing 1.4kg, and the tolerance limits remain as before (upper tolerance: 1.7kg ; lower tolerance: 1.1 kg ). Calculate the process capability index for the weight of the bees packages. Is tyler able to meet the tolerance limits?
