Problem 10-5 (Algo) Using samples of 196 credit card statements, an auditor found the following:Use Table-A. Sample 1 2 3 4 Number with errors 4 3 6 9 Click here for the Excel Data File a. Determine the fraction defective in each sample. (Round your answers to 4 decimal places.) b. If the true fraction defective for this process is unknown, what is your estimate of it? (Round your answer to 1 decimal place.) c. What is your estimate of the mean and standard deviation of the sampling distribution of fractions defective for samples of this size? (Round your intermediate calculations and final answers to 4 decimal places.) d. What control limits would give an alpha risk of .03 for this process?

(c) Based on what we know about Observation B, if the cutoff value is lowered to 0.2, what happens to the values of sensitivity and specificity? Explain. Use the ROC curve to estimate the values of sensitivity and specificity for a cutoff value of 0.2. If required, round your answers to three decimal places. Do not round intermediate calculations. Answer Part C, there are no other parts here. I have the sensitivity already and is equal to 1. What is the specificity??If you are not 100% sure you are right, do not attempt this is frustrating. The cutoff value has changed from 0.5 to 0.2. The sensitivity is 1 which is correct. I need help with the specificity. Sensitivity does not equal 1/14 and specificity does not equal 1/31 so don't answer that and do not answer any other parts just answer part C.
Johnson Plastics Inc. produces cases for CDs. The accounting manager has performed a regression analysis to determine future production costs. The regression estimate is $5,000, with anR-squared of .9, a t-value of 2.5, and a standard error (SE) of $400. Within what interval would shebe reasonably (67%) confident that the actual values will fall?
1. HighQualityasavalueproposition:Paras took on himself to ensure quality becomes a top differentiator and a value proposition to its customers. They started working closely with beekeepers in the Himachali region around the Himalayan foothills and in Muzaffarpur, where they encourage ethical beekeeping. Ethical beekeeping is a format where a hundred per cent of the honey is harvested at no point. Only 60% will be taken out of the hives that, or through that process, at any point, 40% will be left back for the bees.Also, through the exploration and pursuit of pure honey, Paras came across multiflora honey, which is most commonly used as a source of honey. But unfortunately, adulteration happens when a blend of multiflora honey is packaged and sold. Paras ensured that the lab tested the source from which they collected the honey to ensure the promise of purity was kept at every stage. Moreover, while sourcing the honey, the honey twig ensured that it was entirely antibiotic-free.2.…

Vilfredo Pareto was a famous engineer/economist in the 19th and early 20th centuries. He reportedly expressed this 80/20 Rule: 80% of all progress results from 20% of the actions taken. The Pareto Diagram, also called a Juran Diagram, depicts a variant 80/20 Rule: 80% of all production problems come from 20% of the problem areas. a. What kind of statistical chart is the Pareto Diagram? ____ (enter H for histogram, P for probability distribution, T for a Taguchi chart, A for all three of these. N for none of these. b. The value of the Pareto Diagram is its highlighting the areas causing 80% of quality problems. ____ (enter T for true or F for false)

You are welcome to use a spreadsheet). b) Does the correlation imply that the miracle shakes cause weight loss? Identify any possible outliers.

Jim’s Outfitters, Inc., makes custom fancy shirts for cowboys. The shirts could be flawed in various ways, including flaws in the weave or color of the fabric, loose buttons or decorations, wrong dimensions, and uneven stitches. Jim randomly examined 10 shirts, with the following results:Shirt Defects1 82 03 74 125 56 107 28 49 610 6a. Assuming that 10 observations are adequate for these purposes, determine the three-sigma control limits for defects per shirt.b. Suppose that the next shirt has 13 flaws. What can you say about the process now?
