If you were the Vice-President of Quality Assurance, how would you evaluate the appropriate measure for process capability and then assess the capability of the in-control process to meet specifications? Why is this important?
Our company has recently received a few customer complaints that its candles are not lasting the minimum 50 days previously advertised by the company. As the newly hired quality analyst you are planning to construct control charts that will give you a sense of the current status of the production process. To this end you have collected samples from 20 production batches.
Use Microsoft Excel with answer based on both x̄-chart and R-chart plots
-Is the candle production process in control?
-What is your comment regarding the customer complaints?
-Is there any scope of improvement?
Use Microsoft Excel with answer based on both x̄-chart and R-chart plots
What is it important to prove that a process is proven capable before developing statistical control limit ?

- A quality inspector took five samples in five hours, each with four observations, of the length time for glue to dry. The analyst compute the mean of each sample and the computed the grand mean. All values are in minutes. Use this information to obtain three-sigma control limits for means. It is known from previous experience that the standard deviation of the process is 0.02 minutes.

- x and R Control Charts A cereal manufacturer fills cereal boxes to an averageweight of 20 ounces and has an average range of 2 ounces when the filling process is in control. A sample size of 10 boxes is used in evaluating the process.a. What are the CL, UCL, and LCL for the x and R charts?b. A sample with the following 10 measurements was just taken: 20, 21, 19, 18, 19, 21,22, 20, 20, 19. Is the process still in control?arrow_forwardExplain what might cause a process to be out of control in managing quality ?arrow_forwardA process considered to be in control measures an ingredient in ounces. Roberto Baggio, a quality inspector took 20 samples, each with 8 observations as follows: thats in the pictuer after that using this information, obtain three-sigma (i.e., z=3) control limits for a mean control chart and control limits for a range chart, respectively. It is known from previous experience that the standard deviation of the process is 0.693. First: perform all actions and calculations needed to answer the question. All equations/calculations needed to be fully written STEP by STEP. No short calculations or direct answers/results will be accepted. This applies to the calculations for both types of control limits (mean and range). Second: Explain the process followed to identify each type of control limit and any observations made in the problem-solving process. thank you very mucharrow_forward
- Why are most processes not in statistical control when they are first sampled for control chart purposes? *250 words minimum. Thank you!arrow_forward10. To monitor the quality of pepperoni pizzas, a quality control manager collects random samples of pizzas and evaluates them. The process mean and standard deviation for the weight and diameter of pizzas are not known. Which of the following(s) is a correct matching between the type of data collected and the choice of control chart used? Select all correct matchings. Select one: a. The manager weighed the sampled pizzas and constructed a c-chart. b. The manager rated the appearance of sampled pizzas as acceptable or unacceptable and then constructed a c-chart. c. The manager counted the number of pepperonis per each inspected pizza and constructed a mean chart. d. The manager measured the diameter of the sampled pizzas and constructed a range chart.arrow_forwardquality control You are a quality manager in Infinity automotive company, and you are in the processof setting-up a Shewhart control chart, and you have collected five samples from theproduction line, where n= 5. Based on control chart rules you should collect at least20 samples to determine X-bar and R-bar, which will become the center line of yourchart, but you have decided to cut-corners and are planning to base your chart on onlythese five samples. Calculate the value of X-bar and R-bar of these five samples. Thesamples data collected from the production line is given in Table Q4.1. Note n = 5.arrow_forward
- McDaniel Shipyards wants to develop control charts to assess the quality of its steel plate. They take ten sheets of 1" steel plate and compute the number of cosmetic flaws on each roll. Each sheet is 20' by 100'. Based on the following data, develop limits for the control chart, plot the control chart, and determine whether the process is in control. Sheet Number of flaws 1 1 2 1 3 2 4 0 5 1 6 5 7 0 8 2 9 0 10 2arrow_forwardYour supervisor, Lisa Lehmann, has asked that you report on the output of a machine on the factory floor. This machine is supposed to be producing optical lenses with a meanweight of 50 grams and a range of 3.5 grams. The following table contains the data for a sample size of n = 6 taken during the past 3 hours: a) What are the :X-chart control limits when the machine is working properly?b) What are the R-charL control limits when the machine is working properly?c) What seems to be happening? (Hint: Graph the data points. Run charts may be helpful.)arrow_forwardYou work for Raider Data Systems where thousands of insurance records are entered by clerks each day for a variety of client firms. You are in charge of setting control limits to include 99.73% of the random variation in the data entry process when it is in control. Samples that you collected from 20 employees are shown below. You carefully examine 100 records entered by each employee and count the number of errors entered by each clerk. You also compute the proportion defective in each sample. Using a p-chart, what are the upper and lower control limits? Sample Errors Made Proportion Defective 1 4 0.04 2 5 0.05 3 6 0.06 4 3 0.03 5 8 0.08arrow_forward
