A fast-food company is preparing beef patties for their burgers. The lower specification limit for the burger is 43.6 grams and the upper specification limit is 46.4 grams. The standard deviation is 0.5 grams and the mean is 45 grams. Based on the information given above, please answer the following 2 questions. 1.) The process capability index for this beef patty production process p= . Keep TWO decimals in your answer. 2.) Please calculate the PPM for this beef...
The thickness of a part is to have an upper specification of 0.925 and a lower specification of 0.870 mm. The average of the process is currently 0.917 with a standard deviation of 0.005. What is the probability that the product specification will be above 0.90 mm?
A key joint in a precision machining process has a lower specification limit of a width of 0.99 mm and an upper specification limit of 1.01 mm. The standard deviation is 0.005 mm and the mean is 1 mm. The company wants to reduce its defect probability and operate a "Six Sigma process." To what level would this company have to reduce the standard deviation in the process to meet this target? Note: A "Six Sigma process" has a process...
For a key joint, a precision machining process has a lower specification limit of a width of 0.99 mm and an upper specification limit of 1.01 mm. The standard deviation is 0.005 mm and the mean is 1 mm. (a) What is the process capability index for the bottle filling process? (Round the answer to 3 decimal places.) (b) The company now wants to reduce its defect probability and operate a “six sigma process.” To what level would they have...
Given an upper specification limit of 40, a lower specification limit of 25, mean process performance of 30, and a process standard deviation of 3: a. Calculate Cp b. Calculate Cpk c. Is the process performance acceptable – if not, why? d. To identify factors targeting process improvement the design should be set up to explore factors affecting both process mean and process __________________ .
