Webster Chemical’s nominal weight for filling tubes of caulk is 8.00 ounces ± 0.60 ounces. The target process capability ratio is 1.33. The current distribution of the filling process is centered on 8.054 ounces with a standard deviation of 0.192 ounces. Compute the process capability ratios Cp and Cpk to assess whether the filling process is capable and set properly.
There is a contractual provision between an automotive parts company and a supplier of the company that the acceptance level of a lot is AQL = 1.5%. After receiving a lot of N = 2500 parts and performing a double sampling plan, 4 non-conforming parts were identified in the first lot tested and 3 non-conforming parts in the second lot tested.Required:a. Identify the symbolization of the size of the lot sent and the size of the two lots of samples to be checked (n1 and n2).b. Identify the value of acceptance criteria A1, A2 and rejection criteria R1, R2c. State the decision to accept or reject the lot.
