Question: Suppose that following the construction of the x and R
Suppose that following the construction of the x and R control charts in Exercise 6.34, the process engineers decided to change the subgroup size to n = 2. Table 6E.16 contains 10 new subgroups of thickness data. Plot this data on the control charts from Exercise 6.34(a) based on the new subgroup size. Is the process in statistical control?
Answer to relevant QuestionsRework Exercises 6.34 and 6.35 using x and s control charts. The process is out of control on the x chart at subgroup 18. After finding assignable cause, exclude subgroup 18 from control limits calculations: Control charts on x and R for samples of size n- 5 are to be maintained on the tensile strength in pounds of a yarn. To start the charts, 30 samples were selected, and the mean and range of each computed. This yields (a) ...An chart with three-sigma limits has parameters as follows: UCL = 104 Center line = 100 LCL = 96 n = 5 Suppose the process quality characteristic being controlled is normally distributed with a true mean of 98 and a ... and R charts with n = 4 are used to monitor a normally distributed quality characteristic.
