BHC produces bags of cement. The stated weight for a bag of cement is117117 pounds. Customers will accept an occasional bag weighing as little as 105105 pounds, as long as the average weight is at least 117117 pounds. At the same time, BHC doesn't want to give away cement, so it has set an upper tolerance limit of 129129 pounds. The current filling process has an actual process mean of 119119 pounds and a standard deviation of 3.453.45 pounds.
What should be used to assess capability?
A.The process capability index, because the process mean is not centered on the target.
B.The process capability ratio, because the process mean is not centered on the target.
C.The Six Sigma quality, because the process is well controlled.
D. The process capability ratio, because the process mean is centered on the target.
E.
The process capability index, because the process mean is centered on the target.
Homework Answers
The correct answer is: a)
Reason: as per the definition and mathematical formulation, the process capability index can be well used even if the mean of the process is not centred on the target

Consider an imperfect process that produces flour bags that follows a normal distribution, with a standard deviation of 0.8 pounds. You have been tasked with designing the process to minimize your total cost (fixing cost and filling cost). Assume that you produce 250,000 bags per year, and the cost of fixing a bag weighing more than the USL is $0.10 and the cost of fixing a bag weighing less than the LSL is $0.50. The cost of the flour is...

A company packages a bulk product in bags with a 50-pound label weight. During a typical day's operation of the fill process, 22 subgroups of five bag fills are observed. Using the observed data, 1 and Rare calculated to be 52.9364 pounds and 1.6818 pounds, respectively. When the 22 I's and 22 Rs are plotted with respect to the appropriate control limits, the first 6 subgroups are found to be out of control. We found that the elimination of a...

The Pacific Fruit Company has designed its packaging process for boxes to hold a net weight (nominal value) of 9.0 oz of raisins with tolerances of plus or minus 0.5 oz. Given a process mean of 9.00, an average range of 0.57 and a UCL of 1.21 and a LCL of 0, compute the process capability ratio and index. Cp = _____ (Round your answer to 2 decimal places, the tolerance is +/-0.05) Cpk= _____ (Round your answer to 2...

A quality characteristic of interest for a tea-bag-filling process is the weight of the tea in the individual bags. The label weight on the package indicates that the mean amount is 5.64 grams of tea in a bag. Problems arise if the bags are underfilled or if the mean amount of tea in a bag exceeds the label weight. The accompanying data are the weights, in grams, of a sample of 50 tea bags produced in one hour by a...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
