Solution :
Given that ,
mean = = 0.917
standard deviation = = 0.005
P(x > 0.90) = 1 - p( x< 0.90)
=1- p P[(x - ) / < (0.90 - 0.917) / 0.05]
=1- P(z < -0.34)
Using z table,
= 1 - 0.3669
= 0.6331
The thickness of a part is to have an upper specification of 0.925 and a lower...
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...
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...
Engineers have set specifications for a product so that the upper limit of the specification is 6 standard deviations above the population mean and the lower limit of the specification is 6 standard deviations below the population mean. Unfortunately, the engineers are wrong about the actual value of the population mean, it is in fact shifted 2 standard deviations toward the upper limit. Assuming a normal distribution, determine the probability that a part will be out of specification. Report your...
C&A’s potato chip filling process has a lower specification limit of 9.5 oz. and an upper specification limit of 10.5 oz. The standard deviation is 0.3 oz. and the mean is 10 oz. What is the probability that a bag will weigh more than 10.5 oz.? 95.2% 90.4% 9.56% 4.78%
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 __________________ .
10. C&A's potato chip filling process has a lower specification limit of 9.5 oz. and an upper specification limit of 10.5 oz. The standard deviation is 0.3 oz. and the mean is 10 oz. What is the process capability index for the chip filling process?
15. A process has an upper specification of 0.125" and a lower specification of 0.100". If oo = 0.025”, what is the capability index?
A company makes rods with a lower specification of 16.7mm and 21.4mm. The mean of the production process is 17.5mm and standard deviation is 0.27mm. What is the probability that a produced part is too small?
4) The specification for a plastic liner for concrete highway projects calls for a thickness of 6.0 mm 0.1 mm. The standard deviation of the process is estimated to be 0.02 mm. The process is known to operate at a mean thickness of 6.03 mm. Your manager has requested the process produce no more than 3.4 defects per 1 million produced. Calculate Cpk and then determine if the process is capable.
The specifications for a plastic liner for a concrete highway project calls for thickness of 5.0mm +(with a minus sign or line under it) 0.12mm. The standard devaition of the process is estimated to be 0.02mm. a. The upper specifcation limit for this product = (answer needed) mm (round to 3 decimal places) b. The lower specification limit for this product = (answer needed) mm (round to 3 decimal places) c. The process is known to operate at a mean...
