In an automatic filling process 500gms of certain liquid was to be filled in bags. The permissible variation is $\pm$ 5gms. For investigating the process capability 5 bags were taken at random from each batch for 10 successive batches and the following results were found:
| Batch | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
|---|---|---|---|---|---|---|---|---|---|---|
| Mean Gms | 501 | 498 | 500 | 503 | 503 | 500 | 497 | 502 | 503 | 496 |
| Range | 3 | 4 | 2 | 4 | 3 | 5 | 4 | 2 | 6 | 4 |
Take A2 = 0.58, D3= 0, D4= 2.11. Plot the X and R chart and give the conclusion
