Samples f n= 5 units are taken from a process every hour. The x and R values for a particular quality characteristic are determined. After 25 sample have been collected, we calculate x =20 and R = 4.56. (a) What are the ...Control charts for x and R are to be established to control the tensile strength of a metal part. Assume that tensile strength is normally distributed. Thirty samples of size n= 6 parts are collected over a period of time ...Two parts are assembled as shown in Figure 6.28. Assume that the dimensions x and y are normally distributed with means x and y and standard deviations x and y, respectively. The parts are produced on different ...Statistical monitoring of a quality characteristic uses both an x and s chart. The charts are to be based on the standard values m = 200 and sx = 10, with n = 4. (a) Find three-sigma control limits for the s chart.
