The x-bar and S charts (standard values are known) are used to monitor weight (Specifications 100+9). Twenty samples were collected (n=4). Given: X-bar: CL = 101 s chart: CL = 9 The values of process standard deviation and mean are O mean= 100, standard deviation = 9 O mean= 101, standard deviation = 8.2917 0 None O mean= 100, standard deviation = 9.788 mean= 101, standard deviation = 9.788 Clear my choice
