Refer to the Problem . Suppose Tyler changes its processes so that the average package weight is now 1.5 kgs with a new standard deviation of 0.6 kgs. Tyler still markets the packages of bees as weighing 1.4 kgs, and the tolerance limits remain as before. Calculate the process capability index for the weight of the bee packages. Is Tyler able to meet the tolerance limits?
(*) Tyler Apiaries sells bees and beekeeping supplies. Bees (including a queen) are shipped in special packages according to weight. The target weight of a package is 1.4 kgs. Historically, Tyler’s shipments have weighed on average 1.4 kgs, with a standard deviation of 0.15 kgs. Calculate the process capability ratio, assuming the lower and upper tolerance limits are 1.1 kgs and 1.7 kgs, respectively. Is Tyler Apiaries currently able to meet the tolerance limits 99.7% of the time?
