COMPUTATIONAL PROBLEM (Values for a Control Chart)A company that makes balloons controls its production process by periodically takinga sample of 100 balloons from the production line. Each balloon is inspected fordefective features. During the last 6 samples taken, the proportion of defective itemsper sample was recorded, as shown in the image above.Which answer below is correct for the center line, the upper control limit, and thelower control limit, respectively (meaning, in that order)? You will need to carry 4decimal places in your computations.Sample #Percent Defective1.022.013.044.03.01.0256

Garcia's Garage desires to create some colorful charts and graphs to illustrate how reliably its mechanics "get under the hood and fix the problem." The historic average for the proportion of customers that return for the same repair within the 30-day warranty period is 0.09. each month, Garcia track 80 customers to see whether they return for warranty repairs. The results are plotted as a proportion to report progress toward the goal. If the control limits are to be set at two standard deviations on either side of the goal, determine the control limits for this chart. In March, 14 of the 80 customers in the sample group returned for warranty repairs. Is the repair process in control? The UCL Subscript p equals and the LCL Subscript p equals (Enter your responses rounded to three decimal places.)

Garcia’s Garage desires to create some colorful charts and graphs to illustrate how reliably its mechanics “get under the hood and fix the problem.” The historic average for the proportion of customers that return for the same repair within the 30-day warranty period is 0.10. Each month,Garcia tracks 100 customers to see whether they return for warranty repairs. The results are plotted as a proportion to report progress toward the goal. If the control limits are to be set at two standard deviations on either side of the goal, determine the control limits for this chart. In March, 8 of the 100 customers in the sample group returned for warranty repairs. Is the repair process in control?
Output from a process contains 0.01 proportion of defective units. Defective units that go undetected into final assemblies cost $26 each to replace. An inspection process, which would detect and remove all defectives, can be established to test these units. The inspector, who can test 21 units per hour (which matches the current production rate), would be paid $9 per hour, including fringe benefits. Assume that the line will operate at the same rate (i.e., the current production rate) regardless of whether or not the inspection operation is added. A. Without the inspector, what is the current hourly cost of defects? (Round your answer to 2 decimal places.) B. If the inspection operation is added, what would be the cost to inspect each unit? (Round your answer to 2 decimal places.) C. What would be the benefit (or loss) from establishing the inspection process per unit? (Input the amount as a positive value. Round your answer to 2 decimal places.)
VGHC, humanitarian aid service in the Sub-Saharan Africa, operates its laboratory on-site. The lab maintains an inventory of test kits for a variety of procedures. VGHC uses 780 A1C kits each year. Ordering costs are $15 and holding costs are $3 per kit per year. The new price list indicates that orders of fewer than 73 kits will cost $60 per kit, 73 through 144 kits will cost $56 per kit, and orders of more than 144 kits will cost $53 per kit. Determine the optimal order quantity and the total cost.

The historic average for the proportion of customers that return for the same repair within the 30-day warranty period is 0.12 Each month, Garcia tracks 70 customers to see whether they return for warranty repairs. The results are plotted as a proportion to report progress toward the goal.

Instruction: Prepare a check sheet to analyze the data below from customer complaints, then prepare a list of recommendations that will address these complaints. Case: Tip Top Markets Tip Top Markets is a regional chain of supermarkets located in the southeastern United States. Karen Martin, manager of one of the stores, was disturbed by the large number of complaints from customers at her store, particularly on Tuesdays, so she obtained complaint records from the store’s customer service desk for the last nine Tuesdays.

The output from a process contains a 0.02 defective unit. Defective units that go undetected into final assemblies cost $25 each to replace. An inspection process, which would detect and remove all defectives, can be established to test these units. However, the inspector, who can test 20 units per hour, is paid $8 per hour, including fringe benefits. Should an inspection station be established to test all units?a. What is the cost to inspect each unit?b. What is the benefit (or loss) from the inspection process?
Breeze Toothpaste Company has been having a problem with some of the tubes of toothpaste leaking. The tubes are produced in lots of 100 and are subject to 100% visual inspection. The latest 25 lots produced yielded 112 rejected toothpastes. Calculate the central line and control limits to monitor this process?
