  1. A process in control has an estimated standard deviation of 2 mm. The product produced by this process has specification limits of 120 ± 8 mm and a target value of 120 mm.
    1. Calculate the process capability indices Cp and Cpk for the process if the process mean shifts from 118 mm first to 122 mm and then to 124 mm, but the process variability remains the same.
    2. What will be the yield of the process for each of three situations (mean =118, 122, and 124)

A pharmaceutical company producing vitamin capsules desires a proportion of calcium content between 40 and 55 ppm. A random sample of 20 capsules chosen from the output yields a sample mean calcium content of 44 ppm with a standard deviation of 3 ppm. Find the natural tolerance limits of the process. If the process is in control at the present values of its parameters what proportion of the output will be nonconforming, assuming a normal distribution of the characteristic? Calculate...

1 An x̅ chart with a sample size of 4 is used to control the mean of a normally distributed quality characteristic. It is known that process standard deviation is 8. The upper and lower control limits of the chart are 147 and 123 respectively. Assume the process mean shifts to 121. What is the probability that this shift is detected on the first subsequent sample? What is expected number of samples taken before the shift is detected? 2 The...
