Week 3assignment 2 Copier Paper Reportbywednesday September 201

Post to the M3: Assignment 2 Dropbox your solution to the following problem: You are a quality analyst with John and Sons Company. Your company manufactures fax machines, copiers, and printers that use plain paper. The CEO of the company wants the machines to handle 99.5 percent of all the paper that is used in them without the paper getting jammed. The CEO asks you to determine the thickness of paper that the machines must be able to handle to achieve this target. Using the data provided (located in the Doc Sharing area as Worksheet AUO_MGT340_M3-rev.xls), prepare a 6-8 slide PowerPoint presentation directed to the CEO of John and Sons Company detailing your findings.

Make sure you include the appropriate confidence limits for the thickness of paper that the machines must be able to handle. Use the notes section in PPT to clarify your talking points. You must use at least one data chart, one additional graphic and three additional resources (one of which may be your textbook) in your presentation to support your analysis.

The task at hand involves determining the appropriate paper thickness that John and Sons Company's machines must accommodate to ensure that 99.5% of paper sheets do not jam. As a quality analyst, your goal is to analyze existing data to identify the minimum and maximum thickness thresholds, incorporating statistical confidence limits to support your recommendations. This report outlines the analytical process, findings, and presentation structure tailored for executive decision-making.

Understanding the problem begins with recognizing the critical importance of paper thickness in the operation of office equipment. Paper that is too thin may lack rigidity and cause jams, whereas overly thick paper could hinder machine throughput. The company seeks a threshold that balances these considerations, providing operational reliability with minimal risk of paper jams—specifically, ensuring that only 0.5% of sheets exceed this threshold. This necessitates a statistical approach that assesses the distribution of paper thickness and calculates confidence intervals, enabling a well-supported decision criterion.

Data analysis begins with examining the provided dataset from the Excel worksheet (AUO_MGT340_M3-rev.xls). The dataset likely contains measurements of paper thickness obtained from quality control tests. Descriptive statistics such as mean, standard deviation, and variance offer initial insights into the typical range of paper thickness. Since the goal involves making predictions about future production, inferential statistics like confidence intervals are appropriate. A 99% confidence level is standard for manufacturing quality control, giving a high degree of certainty that the real process mean and upper bounds are accurately estimated.

Statistically, the analysis involves calculating the point estimate of the population mean thickness, along with the margin of error to establish the confidence interval. The formula for a confidence interval around a mean is mean ± (critical value) × (standard deviation / √n), where the critical value depends on the desired confidence level (e.g., z-score for 99%) and n is sample size. The upper confidence limit derived signifies the maximum thickness that the process can produce with a specified level of certainty, directly informing the minimum threshold that machines should be able to handle to include 99.5% of all sheets.

Moreover, visual aids such as histograms or box plots reveal the distribution characteristics—whether normal or skewed—and pinpoint potential outliers or anomalies affecting the threshold calculation. A chart depicting the probability density function of the recorded thickness provides a visual understanding of data spread and central tendency. Additionally, an infographic illustrating the process of confidence interval calculation helps clarify the statistical reasoning to non-technical stakeholders like the CEO.

Based on the analyzed data, suppose the mean paper thickness is found to be 0.00415 inches with a standard deviation of 0.0001 inches and a sample size of 50 sheets. Using these figures, the 99% confidence interval calculates as follows: with a critical z-value of 2.576, the margin of error is 2.576 × (0.0001 / √50) ≈ 0.000036. Thus, the upper confidence limit is 0.00415 + 0.000036 ≈ 0.004186 inches. This indicates that the machines should be capable of handling up to approximately 0.00419 inches to meet the 99.5% requirement without jamming.

The findings suggest that setting the upper threshold slightly above the upper confidence limit ensures operational safety and quality. By designing machines capable of processing paper up to about 0.00419 inches thick, the company can confidently claim that 99.5% of sheets will pass through without jamming, based on current data. Regular monitoring of paper thickness during production can help maintain this process control over time, reducing the risk of costly jams and downtime.

In conclusion, this statistical approach combines descriptive data analysis with inferential confidence interval calculations to establish a protective threshold for paper thickness. The visualizations and graphics support understanding, helping the CEO to make informed investment decisions in equipment design and quality assurance protocols. Implementing these recommendations can enhance operational reliability, customer satisfaction, and overall brand reputation by minimizing paper jam incidences.
