Mumbai Mangoworks

Executive Summary:

Mumbai Maharashtra Mango Megaworks turns Alphonso Mangoes into juice. It bottles the juice in two-liter bottles for distribution. They have used two separate processes, Process 1 a standard process, and Process 2 which doubled the maintenance schedule. The goal is to fill each bottle with exactly 2000 ml of juice no more, no less.

Process 1 was within acceptable fill values: X = 1999.35 ml, t = -1.83, & p = 0.0679, α = 0.05. Process 2 was not within acceptable fill values: X = 1999.15 ml, t = -4.81, & p < 0.000, α = 0.05. While Process 1 fell within acceptable levels, more research is suggested as Process 1 had a standard deviation of 8.73 where Process 2 had a standard deviation of 4.33. Figuring out a way to increase the mean for Process 2 would allow for a more consistent final product.

Introduction:

Mumbai Maharashtra Mango Megaworks (we will refer to as Megaworks) purchases Alphonso Mangoes and turns them into several different products for resale. Among the products they produce is mango juice. The juice is packaged in two-liter bottles for shipment to their customers. In their bottling process, more than two-liters in the bottles would mean that they are giving away juice and eroding profits, and less than two liters could result in angry customers. The Megaworks feel they are walking a fine line in danger of putting in too little and too much juice. Their quality control department wants to analyze their procedures to ensure that they are filling the bottles with exactly two liters of juice.

They have two sets of historical data (Appendix A), that they will use to analyze their juice filling procedures. The first set of data captures (600) “Fill Values”, measured in milliliters, this is referred to as “Process 1”. All of the levels recorded were taken utilizing standard fill procedures. Standard procedures involve removing, cleaning, and replacing the fill nozzles during lunch breaks and at the end of each shift....
