The Great Lakes Company, a grocery store chain, purchases apples from a produce distributor in Virginia. The grocery company has an agreement with the distributor that it desires shipments of 10,000 apples with no more than 2% defectives (i.e., severely blemished apples), although it will accept shipments with up to a maximum of 8% defective. The probability of rejecting a good lot is set at .05, whereas the probability of accepting a bad-quality lot is .10. Determine a sampling plan that will approximately achieve these quality performance criteria and the operating characteristic curve.

- To measure the temperature of a ceramic oven at the college of Arts in PTUK a a thermocouple measurement device is used. The thermocouple has a seebeck coefficient of 60uV/C and has an output voltage of 60mV. When the reference point is 21-C the temperature of the measuring junction is Select one a. none b. 979 C c. 929C d.992C e.927 C.arrow_forwardYou are a food specialist in a company that specializes inrefrigerated delicacies, and one of your brands requires beingmaintained at a temperature of 5°C. You determine averagewater activity (aw) at this temperature to be 0.2. One day, you are informed that the cooling systems onone of the delivery trucks carrying your company’s productsmalfunctioned while en route to its destination and it would notbe fixed until the next delivery. The driver has informed you thatthe temperature in the delivery bay of the truck is averaging55°C. You estimate a heat of sorption (Q) of 19 kJ/mol. Calculate the water activity of the brand at this elevatedtemperature and comment on it’s integrity. Should the deliverystill push through? Or should the products be recalled anddisposedarrow_forwardFor each scenario suggest a control that could be used to reduce the risk.

Increasing expenditures for TQM/Six Sigma programs Increasing total worker compensation to levels above the industry average Using 100% "green" (environmentally-friendly) materials to produce branded footwear Avoiding the use of overtime Avoiding competing for contracts to supply private-label footwear to chain retailers (because winning such contracts damages the company's image as a producer of top quality footwear)arrow_forwardIn a process of filling soda bottles 8% of the total is not completely filled, a potential buyer of the product decides to reject a large purchase batch yes to section a sample of 225 bottles the percentage of bottles that are not completely filled is greater than 7% with a probability greater than 85% a) Under these conditions will they buy the lot? justify the answer b) What is the minimum sample size so that the lot is not bought?arrow_forward
- Q7. A rigid vessel having a volume of 0.05 m³ initially contains carbon dioxide gas at temperature 25°C and pressure p. Ethylene gas is allowed to flow into the tank until a mixture consisting of 20% carbon dioxide and 80% ethylene (molar basis) exits within the tank at a temperature of 25°C and a pressure of 100 bar. Determine the pressure p, in bar, using Kay's rule together with the generalized compressibility chart. Answer: 46.6 bararrow_forwardCost-of-quality theories are established by four scholars. The two of them are Crosby and Juran, and they each have different theories, which are: Group of answer choices zero defects and fitness for use fitness for use and zero defects cost of quality and zero defects grades of quality and fitness for usearrow_forwardSCENARIO B: A woodcutting operation has a target (nominal) value of 200 inches and consistently averages 200.1 inches with a standard deviation of .05 inches. The design engineers have established an upper specification limit of 200.25 and a lower specification limit of 199.75 inches.arrow_forward
- Grain dust is pound for pound more explosive than coal dust or gunpowder. Ignited by an electrostatic discharge or other cause, it has ripped apart grain silos and has killed or wounded many workers over the years. When 54 people were killed during Christmas week 1977, grain handlers and the U.S. government finally decided to combat dust accumulation.10 Ten years, 59 deaths, and 317 serious injuries later, a compromise standard was agreed on that designates dust accumulation of one-eighth inch or more as dangerous and impermissible in silos in the United States. Nevertheless, on Monday, June 8, 1998, a series of explosions killed seven workers performing routine maintenance at one of the largest grain elevators in the world, demolishing one of the 246 concrete, 120-feet-high silos that stretch over a length of one-half mile in Haysville, Kansas. Discuss grain facility explosions as a case study of workplace safety and rule making: Which ideas concerning acceptable risk apply here? My…arrow_forward16.
