Control charts for X Bar and R are to be established on a certain dimension part, measured in millimeters.
Data were collected in subgroup sizes of 6 and are given below. Determine the trial central line and control
limits. Assume assignable causes and revise the central line and limits.
Control charts for \( \mathrm{X} \) Bar and \( \mathrm{R} \) are to be established on a certain dimension part, measured in millimeters. Data were collected in subgroup sizes of 6 and are given below. Determine the trial central line and control limits. Assume assignable causes and revise the central line and limits. Instructions: Need to calculate control limits and central lines for \( X \)-8ar and \( R \) charts. show all calculations and formulas for calculation using Microsoft word then use an Excel sheet to build your charts showing all tables and codes. Note: Submit both Excel sheet and Word document.
