Process Capability In-Class Exercise
1. 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 1.5 kgs, with a standard deviation of 0.10 kgs. Calculate the process capability, 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?
2. Suppose Tyler improves its processes so that the average package weight is now 1.4 kgs with a new standard deviation of 0.06 kgs. The tolerance limits remain as before. Is the new process capable 99.7% of the time?
3. Referring to problems 1 and 2 above, what would the standard deviation have to be for Tyler Apiaries to achieve Six Sigma quality levels (+/- 6 sigma) regarding the weight of the bee packages?
