- Problem 1Human visual inspection is necessary in many quality engineering contexts and is naturallysubject to subjectivity. This is especially true for the inspection of solder joints on circuit boards,as there are numerous types of solder defects, as well as a degree to which a joint possessesone or more defect. Consequently, even highly trained inspectors can disagree on the status ofa particular joint. In a batch of 10,000 such joints, inspector A found 724 to be defective,inspect B found 751 to be defective, and 1159 of the joints were judged to be defective by atleast one of the inspectors. Suppose that one of the 10,000 joints is randomly selected.a. What is the probability that the selected joint was judged to be defective by neither ofthe two inspectors?b. What is the probability that the selected joint was judged to be defective by inspector Bbut not by inspector A?Create the appropriate fully labeled Crow’s Foot ERD.

- Seneca Hill Winery recently purchased land for the purpose of establishing a new vineyard. Management is considering two varieties of white grapes for the new vineyard: Chardonnay and Riesling. The Chardonnay grapes would be used to produce a dry Chardonnay wine, and the Riesling grapes would be used to produce a semidry Riesling wine. It takes approximately four years from the time of planting before new grapes can be harvested. This length of time creates a great deal of uncertainty concerning future demand and makes the decision concerning the type of grapes to plant difficult. Three possibilities are being considered: Chardonnay grapes only; Riesling grapes only; and both Chardonnay and Riesling grapes. Seneca management decided that for planning purposes it would be adequate to consider only two demand possibilities for each type of wine: strong or weak. With two possibilities for each type of wine it was necessary to assess four probabilities. With the help of some forecasts in…Theme Park (5S-7A) The lease of Theme Park, Inc., is about to expire.

- 4. One of the key concept in CRM is the Life Time Value (LTV) of a customer. Let's assume that we are acompany that sells coffee and snack and Tom is our customer. Calculate Lifetime Value (LTV) of Tom withthe Custom LTV Equation way ( https://blog.kissmetrics.com/how-to-calculate-lifetime-value/ ) . Tom 'saverage expenditure per visit is $10 and Tom visited us 10 times per week on average. A customer usuallyremains as a customer for 3 years (i.e., the average customer lifespan is 156 weeks (3 years *52 weeks peryear) and profit margin per customer is 10% on average.10 Dr. Lillian Fok, a New Orleans psychologist, specializes in treating patients who are agoraphobic (i.e., afraid to leave their homes).
