**Control Chart Analysis for Defects Monitoring in Jean Production**Judy Holmes Textiles is implementing a c-Chart to monitor defects per pair of jeans in their manufacturing process. This chart includes 3-sigma control limits. An operations manager samples one pair at 10 different time periods to count defects.**Step 1 of 7:** Determine the Center Line of the control chart. Round your answer to three decimal places.**Data Table:**- **Sample 1:** 9 defects- **Sample 2:** 14 defects- **Sample 3:** 3 defects- **Sample 4:** 10 defects- **Sample 5:** 15 defects- **Sample 6:** 15 defects- **Sample 7:** 11 defects- **Sample 8:** 11 defects- **Sample 9:** 14 defects- **Sample 10:** 10 defectsTo calculate the Center Line, you can use the provided feature to copy the table or find the average of the selected cells. The average number of defects from the samples is 9.000.This information guides the quality control process, ensuring that the production remains within acceptable defect limits.

The number of defects in 10 samples is given as follows:SampleDefects19214334105156157118119141010
