1.A product specification for a critical measurement is 120 +/- 0.2 millimeters. What is the length of the specification interval?
2.A product specification for a critical measurement is 120 +/- 0.2 millimeters.
If we need a six sigma process in making this product, what should be the standard deviation allowed for the process? (please provide three decimal places)
3.In the production process of an integrated chip, it is seen that 80% on average are good. From a newly created batch, 200 chips were randomly tested. What is the upper control limit for the proportion of defective items for this sample?
(give the proportion as a decimal number - not a percentage - with three decimal places)
4.A restaurant on average serves 70 patrons each night. Assuming there is only the inherent variability in the number of patron served, what is an upper control limit for the number of patrons to be served.
A product specification for a critical measurement is 120 +/- 0.2 millimeters.
If the process has a standard deviation of 0.08 mm, what is the length of the process interval (that is, what is the length of the interval in which we can expect 99.7% of the output to be?)
