Question: Lee Flower Company is a flower producer located in Auburn. It has a large contract with Wal-Mart to supply azaleas to the stores in the southeast region of the country. From past sales data, it has become evident that the larger, healthier plants sell better than the smaller plants. Thus, the flower producer wants to improve the growing process so that they will have larger, healthier azaleas. Wal-mart is very tough on their suppliers to provide large, healthy azaleas because they don’t want a lot of small, weak plants in inventory after the planting season has passed. Thus, Wal-Mart’s expectations are that the plants must have a composite score of 9 +/- 2 inches. (They have an upper limit on the size because they want to get as many flowers on the shelves as possible.) The green thumbs went out and measured 100 plants at random. This data is in the column named “Benchmark”. Comment on the Sigma level (both long and short term). Also, how many out of a million would you expect to be below the Wal-mart spec and how many out of a million would you expect to see above the Wal-Mart spec. What recommendations would you make for improvement? Note: the larger the score the better.
