Consider the x and R charts you established in Exercise 6.7 using n = 5. (a) Suppose that you wished to continue charting this quality characteristics using x and R charts based on a sample size of n =3. What limits would be ...Control chart for x and R are maintained on a process. After 20 preliminary subgroups each of size 3 are evaluated, you have the following data: (a) Set up control charts using these data. (b) Assume that the process ...A TiW layer is deposited on a substrate using a sputtering tool. Table 6E.14 contains layer thickness measurements (in angstroms) on 20 subgroups of four substrates. (a) Setup x and R control charts on this process. Is the ...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) ...A hospital emergency department is monitoring the time required to admit a patient using x and R charts.
