Certainly! Here the question-wise answers and a final summary on the given data: --- ##-wise Answers ### a. Calculate the mean and range for the above samples. | Number | Mean | Range |-----------------|--------|--------| | 1 | 101.2 | 17 | | 2 | 995.2 | 20 | | 3 | 102.4 | 12 | | 4 | 1021. | 20 | | 5 | 996.4 | 22 | | 6 | 102.4 | 19 | | 7 | 987.4 | 16 | | 8 | 1011.4 | 14 | | 9 | 1002.8 | 20 | | 10 | 998.4 | 21 | | 11 | 998.8 | 21 | | 12 | 100.8 | 23 | | 13 | 100.4 | 13 | | 14 | 998.2 | 22 | | 15 | 998.4 | 18 | *(Values are rounded to 3 decimal places)* --- ### b. Determine \( \bar{X} \) and \( R \). - **Mean (\( \bar{X} \))**: 1001.4 - **Average Range (\( R \))**: 19.4 *(Rounded to 3 decimal places)* --- ### c. Determine the UCL and LCL for an X̄-chart. - **UCL**: \( \bar{X} + A_2 \times R \) - **LCL**: \( \bar{X} - A_2 \times R \) Assuming \( A_ = .729 \): - UCL = 1001.4 + .729 × 19.4 ≈ 1001.4 + 14.14 ≈ **1015.540** - LCL = 1001.4 - 14.14 ≈ **987.260** --- ### d. Determine the UCL and LCL for an R-chart. - UCL = D4 × R̄ - LCL = D3 × R̄ Assuming \( D_3 = \), \( D_4 = 2.282 \): - UCL = 2.282 × 19.4 ≈ **44.271** - LCL = × 19.4 = **** --- ### e. Comments on the process. **Answer:** The process is **in statistical control** because all sample means are within the control limits, and the process variation appears consistent over time. --- ## Final Summary - The calculated mean of sample readings is approximately **1001.4**. - The average range is **19.4**. - Control limits for the X̄-chart are approximately **UCL = 1015.540** and **LCL = 987.260**. - Control limits for the R-chart are approximately **UCL = 44.271** and **LCL = **. - The process appears to be in **statistical control** based on the sample data and control limits. --- Let me know if you'd like detailed calculations for each sample or clarification!
