Question
An estimate the capability index C_mu is: 0.65. 0.32. 1.55. 3.92. Which of the following statements is TRUE? A subgroup is a sample from the process of interest. Rational subgroups are chosen in such a way that individual observations within subgroups have been measured u dissimilar process conditions. Subgroups are usually large. All the statements are true. None of the statements is true. Which of the following statements is NOT true? An in-control process is one that mostly meets design specifications or tolerance. All Control charts can be used both retrospectively and prospectively. If all the points on a control chart fall within the control limits, the process is said to be in control. External standards are unrelated to the internal state of the process without exception.Explanation / Answer
Ans: 30)Option B is true
31)Option A is not true.
29)C)1.55(other three values are not valid)
However where a process produces a characteristic with a capability index greater than 2.5, the unnecessary precision may be expensive..
Situation Recommended minimum process capability for two-sided specifications Recommended minimum process capability for one-sided specification Existing process 1.33 1.25 New process 1.50 1.45 Safety or critical parameter for existing process 1.50 1.45 Safety or critical parameter for new process 1.67 1.60 Six Sigma quality process 2.00 2.00
