Obg'ecmve III: 1. An employee is responsible for collecting manufactured battery sample of size between 50 and 60 every day at 4 pm for a period of consecutive 25 days every 3 months, and collect data on the daily number of defective batteries. A relevant quality control chart is given in Figure 1. Control Chart 0.12 0.1 MI 0.5 :3; W 1 2 3 a 5 6 I a 9 101112131&1516111319202122232425 +Musurl *Contat +LCL +UCI. Figure l. . According to customer specications. standard AA battery length should be between 49.0 mm and 50.5 mm. Assuming the lengths to be normally distributed, the average and the standard deviation of the lengths are 49.9 mm and 0.2 mm, respectively. 3. Objective III: [2] What type of control chart is drawn in Figure l? Justify. [1] What measure (joined by the red line) is plotted in Figure l? [2] What do you infer about the procas from Figure 1? Justify. [1] What does the center line represent in Figure l? [1] Is the process distribution with respect to battery length centered? Justify. [3} Calculate relevant process (with respect to battery length) capability index value and comment on the process capability. \"PE-"\"997.\
