A control chart for the fraction non-conforming of muffler bearing production is maintained with a p value of 0.10 and a sample size of 75. What is the UCL [a], and the LCL [b]? What is the probability that a shift in the fraction non-conforming to 0.14 is detected in the first sample [c]? What is the minimum sample size for the LCL to be greater than zero [d]?
