34. Studies on a machine that molds plastic water pipe indicate that when it is injecting 10-inch diameter pipe, the process standard deviation is 0.667 inches. The ten-inch pipe has a specification of 10-inch plus or minus 1.0 inch. What is the process capability index if the process sample mean is 10 inches? A. 0.50 B. 0.67 C. 1.00 D. 2.00 35. The specification limits for a product is 80 cm and 101 cm. A process that produces the product has a mean of 95 cm and a standard deviation of 2 cm. What is the process capability index? A. 1.00 B. 1.67 C. 0.83 D. 2.00 36. Juan needs to create a p-chart for a process. Juan takes 20 samples. Each sample is 100 units. Juan records a total of 201 defects. Using a z-score of 3.0, what is the upper control limit (UCL) for the p-chart? (You can round your p-bar and Sp to 4 decimal places) A. 0.0102 B. 0.0319 C. 0.1125 D. 0.1908
