A well-known theoretician at Institution A is called by an experimentalist at Institution B to discuss what appears to be a new discovery, based on a highly original approach to the measurements in question. The discovery supports the theorists highly controversial approach to the problem. However there is a substantial amount of work needed before the results can be submitted for publication. The theorist has been invited to present a seminar at Institution C, where she is a candidate for a position, and where competitors of the experimentalist at Institution B are found. She was not told explicitly that his conversation with the experimentalist at Institution B was privileged.Questions What should she do in preparing for his visit? What are the potential conflicts of interests? What ethical considerations should the theorist consider in preparing her talk? Are there other actions that she could or should take in preparing for the visit? [OR]Suppose you have a strong interest in…

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
In 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?

- 1. Suppose that you are an ammunition manufacturer and that your manufacturing process yields a true % of defects of 2.5%. The probability of accepting a lot of 40,000 cartridges for a sample of 3000 with 15 defects is 85%. The AOQ for this set of 40,000 cartridges is _____ %. 2. You are the process improvement manager and have just purchased a metal sheet roller to form gasket material for high-performance engines. You are excited because the company's goal is 6 sigma (no more than 3.4 defects per million) and this machine may be the innovation that you need. The gaskets cannot be more than 0.0002 in from the required thickness of 0.025 in. You want to know if you should replace the existing roller that has a Cpk = 1.0. The new sheet roller has a Cpk = ___. Round the answer to 2 decimal places.arrow_forwardThinking of a manufacturing company, how might probability be a part of their quality control?

- A quality engineer has a manufacturing specification (in cm) of 0.25 plus or minus 0.05 Historical data indicates that if the quality characteristic takes on values larger than 0.3 cm or smaller than 0.2 cm, the product fails and a cost of $90 is incurred. Determine the Taguchi Loss Function and estimate the loss for a dimension of 0.15 cm.arrow_forwardRepresentatives of the Patriot Insurance Company take medical information over the telephone from prospective policy applicants prior to a visit to the applicant’s place of residence by a registered nurse who takes vital sign measurements. When the telephone interview has incorrect or incomplete information, the entire process of approving the application is unnecessarily delayed and has the potential of causing loss of business. The following data were collected to see how many applications contain errors. Each sample has 200 randomlyselected applications. Sample Defects Sample Defects 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 20 18 29 12 14 11 30 25 27 16 25 18 25 16 20 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 15 40 35 21 24 9 20 17 28 10 17 22 14 19 20 a.

- A certain reagent is created to test for an infectious disease. The test has anaccuracy rate of p = 90%, and the accuracy does not depend on whether or not thepatient is actually infected. a. If four people are tested for the disease, what is the probability that at leastthree of them receive accurate test results? b. In an area where q = 5% of people are infected, a man’s test result ispositive. What is probability that it is a false positive (which means that he is notinfected but the test is positive due to inaccuracy)? *please solve for a-b, type or neatly write your answers on paper, NO EXCEL* thank you !arrow_forwardA toy manufacturer wants to apply Six Sigma to its manufacturing process. The product will be examined by the inspection team using a predetermined standard. A product is considered defective if it doesn't satisfy a requirement. Each item may have as few as no flaws or as many as six. One product was discovered to be faulty after the inspection crew examined roughly 1000 goods. Determine the DPMO for the process and provide feedback on its suitability for six sigma.arrow_forwardConsider a component that fails in THREE failure modes. Each failure mode follows a Weibull distribution function whose scale and shape parameters values are reported in the Table below: Scale Parameter Shape Parameter Failure Mode 1 7000 1.7 Failure Mode 2 10000 Failure Mode 3 12000 If the manager requires to have 0.99 component reliability at 1000 hours of operation. Determine the percentage of improvement required for each failure model in order to achieve this goal, by resorting to Competing Risk Model.arrow_forward
- 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.arrow_forwardA 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.arrow_forwardA machine produces parts that are either good (90%), slightly defective (2%), or obviously defective (8%). Produced parts get passed through an automatic inspection machine, which is able to detect any part that is obviously defective and discard it. What is the quality of the parts that make it through the inspection machine and get shipped?arrow_forward
