In a large sample of Zesticola cans, the average amount of caffeine was found to be 45 milligrams. The bottling process that produced these cans is a. Centered b. Minimally capable c. Six-Sigma capable d. Not centered Question-2: A particular kind of cement must dry within 3 to 5 minutes. A study showed that the drying time of Quik-Dry Cement had a standard deviation of 0.2 minutes Is the process that manufactures Quik-Dry capable of mecting drying time specifications? Pick one of the following responses. Process is minimally capable Process is not minimally capable e Cannot answer without more information a Process is Six-Sigma capable Question-3: According to FAA standards, the landing process for a plane must take between 3 and 5 minutes. For Brogan Airport the average landing time is 3.5 minutes with a standard deviation of 0.2 minutes. Calculate the appropsiate measure of capability and pick one of the following response a. 1.67, Brogan Airport is capable b. 2.50, Brogan Airport is 6-Sigma capable c. 0.83, Brogan Airport is not capable d. 1.00, Brogan Airport is minimally capable Question-4: A Cpk index of 1.00 equates to what defect rate? five percent 3.4 defects per million items c2.7 defects per 1,000 items 97.23 percent e one percent Question-5: The statistical definition of Six Sigma allows for 3.4 defects per million. This is achieved by what Cpk index value? 1.33 1.67Explanation / Answer
Question 3)
USL = 5
LSL = 3
Mean = 3.5
SD = 0.2
Cp = USL – LSL / 6 sigma
Cp = 5 - 3/6*0.2
Cp = 1.67
Cpk = min (USL-Mean / 3 sigma, LSL – Mean / 3 sigma)
Cpk = min (5 – 3.5 / 3 * 0.2, 3 – 3.5 / 3 * 02)
Cpk = 0.83
Answer is option c = 0.83, Borgan Airport is not capable because Cpk is less than 1
