Transcribed Image Text:The data shown below were collected on the number of nonconformities per unit for 10 time periods. Complete (a) and (b).
| Time | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
|--------------------------|---|---|---|---|---|---|---|---|---|----|
| Nonconformities Per Unit | 6 | 3 | 7 | 4 | 4 | 5 | 4 | 5 | 2 | 0 |
a. Construct the appropriate control chart and determine the UCL and LCL.
- What is the upper control limit? Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
- ⃝ A. UCL = ___ (Round to three decimal places as needed.)
- ⃝ B. The control limit does not exist.
- What is the lower control limit? Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
- ⃝ A. LCL = ___ (Round to three decimal places as needed.)
- ⃝ B. There is no solution.
![The data shown below were collected on the number of nonconformities per unit for 10 time periods. Complete (a) and (b).

**Which of the following is the correct control chart?**
- **A.** [Graph A]
- X-axis: Time (0 to 10)
- Y-axis: Nonconformities (0 to 12)
- Control limits are marked with UCL (Upper Control Limit) and LCL (Lower Control Limit).
- The blue line with data points stays within control limits, showing fluctuations but no clear pattern.
- **B.** [Graph B]
- X-axis: Time (0 to 10)
- Y-axis: Nonconformities (0 to 12)
- Control limits are marked with UCL and LCL.
- The blue line shows an upward trend that approaches the UCL, indicating potential variation.
- **C.** [Graph C]
- X-axis: Time (0 to 10)
- Y-axis: Nonconformities (0 to 12)
- Control limits are marked with UCL and LCL.
- The blue line fluctuates significantly, with some points close to control limits yet remaining within.

**b. Are there any special causes of variation?**
- **A.** There do not appear to be special causes of variation, as there are no points outside the control limits and no discernable pattern.
- **B.** There appears to be a special cause of variance, as there is a discernable pattern.
- **C.** There appears to be a special cause of variance, as there are points outside the control limits.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc91d435c-8a20-4fa9-b80f-5aaeb9e13244%2Ff0452dfd-19db-44a4-98c4-e82bac869ba5%2Fkc37br_processed.png&w=3840&q=75)
