a)
To determine: The type of control chart that would be useful to monitor the process.
Introduction: Control charts used to determine whether the process is under control or not. Attributes and variables are the factors under the control charts.

- Please do not give solution in image format thanku what is the upper and lower limit answer asaparrow_forwardWould a data series that contains values grouped into 10 categories be better displayed as a pie chart or a column chart?arrow_forwardThe IRS is concerned with improving the accuracy of tax information given by its representatives over the telephone. Previous studies involved asking a set of 25 questions of a large number of IRS telephone representatives to determine the proportion of correct responses. Historically, the averageproportion of correct responses has been 72 percent. Recently, IRS representatives have been receiving more training. On April 26, the set of 25 tax questions were again asked of 20 randomly selected IRS telephone representatives. The numbers of correct answers were 18, 16, 19, 21, 20, 16,21, 16, 17, 10, 25, 18, 25, 16, 20, 15, 23, 19, 21, and 19. a. What are the upper and lower control limits for the appropriate p-chart for the IRS? Use z = 3. b. Is the tax information process in statistical control?arrow_forward
- How is a process operating in statistical control distinguished from one that is notarrow_forwardSuppose that you are using a p chart to monitor the percentage of times that you fail to get phone numbers at bars. Each day for 30 days you ask 15 different people for their phone number. On average, 6 people declined to give you their phone number each day. What would be the upper control limit for the p chart?arrow_forwardYou hear that your competitors are using a control device called "blinc receiving." What is blind receiving? Under what conditions would you use this procedure?2.arrow_forward
- Would a data series that contains values grouped into 10 categories be better displayed as a pie chart or a column chart? explain whyarrow_forwardWhat is the difference between Lot Quality Assurance Sampling (LQAS) and Routine Data Quality Assessment (RDQA) What is the relationship between the LQA and RDQA in improving data quality and data collection?arrow_forward2. An ad agency tracks the complaints, by week received, about the billboards in its city: Week No. of Complaints 1 4 2 5 3 4 4 1 5 3 6 9 7 4 8 5 9 4 10 21 11 3 12 9 What type of control chart would you use to monitor this process and why? What are the three-sigma control limits for this process? Assume that the historical complaint rate is unknown. Is the process mean in control, according to the control limits? Why or why not? Assume now that the historical complaint rate has been four calls a week. What would the three-sigma control limits for this process be now? Is the process in control according to the control limits?arrow_forward
- Which components of variation do control charts seek to separate? Attributable variation from natural variation Process variation from product variation Attributable variation from process variation Natural variation from process variation Process variation from Total variationarrow_forwardThe temperature of a burrito served to a customer in a local Mexican restaurant A: Discrete B; Continousarrow_forwardWhat would the Sp value be?arrow_forward
