- Which of the following is NOT true when a process is in-control select one: a. the process includes a high precentage of satisfactory results b. the process includes random variation c. All points lie within the control limits d. the process includes variation due to special or assignable causes50 motor generators are inspected per day from a stable process. The best estimate of the fraction of nonconforming is 0.076. Determine the centeral line and control limits. On a particular day, 5 nonconforming generators were discovered. Is this process in or out of control? For the information given in the problem, construct a np-chartState True or False for the below two statements. 1. The purpose of process control charts is to detect the presence of natural variations. 2. Unlike process capability ratio (Cp), process capability index (Cpk) can possibly be negative.
- A small electronic device is designed to emit a timing signal of 200.0 milliseconds (ms) duration. This device is specified as 201.0 + 10.0. In the production of this device, subgroups of six units are taken at periodic intervals and tested. Xbar and R are calculated for each subgroup and used to plot control charts. The results of inspection of 25 subgroups, ΣX = 5,000.00 and ΣR = 277.00. Determine the control limits for Xbarand R charts, and estimate the value of σ.Please do not give solution in image format thanku A restaurant wants to make sure that they are serving customers quickly enough. Every day for 10 days, they sample 16 random customers, and measure how long it is until the waiter shows up. Uisng this sample data, the company calculates the 3-sigma control limits as LCL = 3.5 minutes and UCL = 6.5 minutes. What would be the LCL and UCL if the company uses 2-sigma control limits instead? 1. LCL = 4.5 minutes and UCL = 7.5 minutes 2. LCL = 3 minutes and UCL = 7 minutes 3. LCL = 4 minutes and UCL = 6 minutes 4. LCL = 4.5 minutes and UCL = 5.5 minutesA pharmaceutical company producing vitamin capsules desires a proportion of calcium content between 40 and 55 ppm. A random sample of 20 capsules chosen from the output yields a sample mean calcium content of 44 ppm with a standard deviation of 3 ppm. Find the natural tolerance limits of the process. If the process is in control at the present values of its parameters, what proportion of the output will be nonconforming, assuming a normal distribution of the characteristic? Answer letters a, b, and c. a. Find the Cp index. Comment on the ability of the process to meet specifications. b. What proportion of the specification range is used up by the process? c. If it is easier to change the process mean than to change its variability, to what value should the process mean be set to minimize the proportion of nonconforming product?

Occasionally a test yields inconclusive result and must be repeated. Using the following 15 sample results for the number of retests in n = 150 observations each, determine the control limits for the proportion of retests. Use three sigma (standard deviations) limits. Is the process in control? Why/why not? (Round answers to 4 decimal places.)At Webster Chemical Company, lumps in the caulking compound could cause difficulties in dispensing a smooth bead from the tube. Even when the process is in control, an average of four lumps per tube of caulk will remain. Testing for the presence of lumps destroys the product, so an analyst takes random samples.
