|
| Sample 1 | Sample 2 | Sample 3 | Sample 4 | Sample 5 | Sample 6 |
| Loaf # 1 | 5.94 | 6.66 | 5.70 | 5.22 | 5.94 | 5.22 |
| Loaf # 2 | 6.30 | 6.84 | 5.40 | 7.02 | 6.48 | 6.30 |

| Loaf # 4 | 5.10 | 7.20 | 5.10 | 5.10 | 5.40 | 5.40 |
Provide the following values: X-double bar = R-bar = You are asked to compute 3 control limits for X-bar and Range charts. Provide the following values: A2 = D3 = D4 = For X-bar Chart, LCL = UCL = For R-Chart, LCL = UCL = Is the process under control? (Enter YES or NO): NOTE: All values should be rounded to the nearest hundredth (two decimal after dot, for example 9.99)
