Question 2. An automobile manufacturer wishes to control the number of nonconformities in a subassembly area producing manual transmissions. The inspection unit is defined as four transmissions, and data from sixteen samples (each of size 4) are shown in Table. (a) Find UCL and LCL of control chart for nonconformities per unit (use L=3) Do these data come from a controlled process? If not, assume that assignable causes can be found for all out-of-control points and calculate the revised control chart parameters. (B) If the process is shifted to & = 3, what is the average run length? Sample Number |Number of Nonconformities 1 2 1 0 NHNONNWH W N HEN 16
