1. The trading partners (such as suppliers, distributors and logistics service providers) are not part of the value stream of an organization. True False 2. A Total Quality Management (TQM) system systematically, sustainably and deliberately exposes hidden problems in an organization. True False 3. From a perspective of Statistical Process Control (SPC), a six-sigma process will have which of the following attributes? a) The USL and LSL will be separated by a distance of six sigma b) The process center will be aligned with the LSL c) The number of defects produced by the process will be 0.0018 parts per million d) All of the above
Using traditional methods, it takes 101 hours to receive a basic driving license. A new license training method using Computer Aided Instruction (CAI) has been proposed. A researcher used the technique with 100 students and observed that they had a mean of 102 hours. Assume the variance is known to be 16. A level of significance of 0.05 will be used to determine if the technique performs differently than the traditional method. Find the value of the test statistic. Round your answer to 2 decimal places. Enter the value of the test statistic.
Hydronos is a Greek manufacturer of yogurts that have gained popularity in the United States, so it has recently built a U.S. production plant and distribution center. To ensure that it complies with U.S. environmental standards, Hydronos is planning to implement efforts to reduce emissions and other industrial waste at its manufacturing plants using a program called Green-100. Green-100 covers all company procedures, from reducing manufacturing emissions, to how the lights are controlled in the plant, to how the truck drivers complete their routes. For example, under the new Green-100 guidelines, Hydronos has measured the amount of fuel drivers need to complete their routes for traveling at moderate speeds. If drivers choose to drive at higher speeds, they will need to pay for any extra fuel they use. Hydronos also has plans to install speed governors in its fleet of trucks to ensure that the drivers do not exceed speeds of 80 miles per hour. Mangements' claim that the new technology…

A manager wanted to predict how much rework time would result from taking a manufacturing line from producing 8 hours a day to 24 hours a day. The manager carefully analyzed three years of performance from manufacturing lines that operated 8 hours a day to make the prediction. The manager is at risk of making what type of error? a Data overfitting error. b Extrapolation beyond the range error. c Outlier error. d Either a type I or type II error.
please answer this question in 30 minutes. Suppose that you are the manager of JCPenney store. Your goal is to increase and control the rate at which store cashiers can successfully sign customers up for JCPenney credit cards. To this end, for each of the eight store cashiers, you observed 50 interactions where the cashier made an attempt to sign a customer up for credit card. The data showed that there was a total of 16 cases in which the cashiers could successfully sign the customer up for a credit card. Now, if you do not want the lower limit to be below .0052, what z-value would this imply? How confident can you be that the actual lower limit is greater than or equal to .0052?
Your MD called you in his office today and said that, “I have observed that most of the performance appraisers are not doing justice to their role as appraisers. Mostly, they are committing following errors: a) Halo Error. - b) Central Tendency Error. c) Spillover Error. MD wants you to write down a clear example for each error.
Mr. Ferdinand is a well-known entrepreneur who sells fresh organic beef to persons in the localcommunity. Customers love the quality of meet that Mr. Ferdinand sells so they tend torecommend his product to other people. Recently, Mr. Ferdinand has been running out of beefto sell to his customers. One customer suggests to him that he must use past sales records toforecast demand for his beef so that he can meet his customers' demand.I. Using a numerical example, demonstrate to Mr. Ferdinand how he can use a three-week and a four-week weighted moving average to forecast demand for his beef.II. Show how Mr. Ferdinand can test the accuracy of his forecast. III. Explain to Mr. Ferdinand two ways in which he can benefit from doing a forecast for his beef.
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?
Please Answer Quality Management Question A milling machine has an expected life of 10 years from the time it is installed into a production line. Assume the exponential distribution is appropriate. What is the probability that the machine will fail between 5 and 12 years after being installed into the production line? Suppose the three milling machines were designed in parallel into the production line system. What is the probability that the production line system will survive 10 years?
