assignment description
After the completion of the IDL3 preliminary (attached) and final assignments, you will have completed a probabilistic analysis and presented the findings as an Expert Witness in a memorandum as one piece of evidence in litigation in the role of an Expert Witness. This document will be sent to the Court involved with a lawsuit that involves the product you will be evaluating. For this purpose, you will address your memorandum to the Judge. However, it must be understandable to the jury who will reference it, and it is also likely to be referenced by the lawyers on both sides of the litigation.
Problem
In 2016, the City of Sontse, Florida, installed porcelain tile in 45 of the neighborhood community centers in the city. City managers wanted to upgrade the facilities’ quality to rent them out for private functions. Designers working on the renovations selected Porcelain tile manufactured by Anato Porcelain for all floors because of its upscale appearance, durability, and slip-resistant properties. However, city leaders were concerned about users slipping on these floors due to the likelihood of wet floors from spills, plumbing issues, and water blowing in during heavy rainfall. Because of this, designers required that the new ceramic tile floors meet the American National Standards Institute ANSI B101.3 test method for measuring the wet dynamic coefficient of friction (DCOF) of Hard Surface Walkways. This test requires the floor to meet a dynamic coefficient of friction measurement equal to or greater than 0.42 under prescribed wet testing conditions.
The quantity of tile ordered from Amato required a 5% overage on the tile needed for the initial installation to be delivered to each location as part of the installation process. This overage was stored at each location to be available for replacement of porcelain that might be needed over the life of the installation.The tiles for the testing were taken from these boxes so that there would be no chance of sealer or cleaning chemicals being on them.
However, since installers completed the new ceramic flooring installation, slip-and-fall accidents in these community centers have increased substantially. A report on the local news made residents aware of the extent of the problem, prompting the city to sue Anato Porcelain, claiming the ceramic tile manufacturer provided does not meet the required standard for slip resistance. They are requesting that the manufacturer provide new porcelain tile, pay for testing it before installation, and pay for removal and reinstallation of the new porcelain tile. The manufacturer claims their product did meet the test standards, suggesting that the installers’ application of unapproved sealers or maintenance staff using incorrect cleaning materials post-installation can also cause the problem.
The judge overseeing the case had an independent investigation company, Floor Testing Inc., measure a sample from the extra tiles for each community center to evaluate the claim. You have also been hired as an independent expert witness to evaluate if the ceramic tile provided by the manufacturer likely met or failed to meet the required standard. Your contract is for services as an ordinary fact witness. You will report the result of your data analysis with 95% confidence in a memorandum to the judge, who will provide it to the jury hearing the case.
You will provide your findings in a memorandum addressed to the judge, Tanya Wasilew, and copied to the Clerk of the Court, Daniel Taft, defense attorney, Mitch Soldano, and the plaintiffs’ attorney Amira Herana. Use Data attached
problem support information
The information below is to assist you in understanding the product and process described in this problem.
The Product, its Distribution, and Installation.
When you see porcelain tiles on the floor, it will likely have gone through the hands of several organizations listed below:
Manufacturer – Porcelain tile is a product manufactured in highly specialized plants. It is a more complex manufacturing process than ceramic tile. However, it is a product that holds up better to heavily trafficked applications. Manufacturers develop recommended installation methods for their products to ensure their performance. However, most do not get involved in the installation of their product.
Shipping and Distribution/retail sales – Getting the product from the plant to the installer is most often handled by independent shipping companies, distributors, and retailers. How the product was transported from the manufacturer to the distributor or retailer and then to the job site is not information needed for this assignment.
Installers – Ideally, products are installed by skilled craftspeople who are familiar with all the installation methods necessary for successful long-term flooring performance. They are typically in businesses independent of the tile manufacturer whose product they install.
Read the problem carefully to understand who is involved in the lawsuit and, more specifically, who is involved in the question you are answering to contribute to the case.
Porcelain Tile Manufacture
Dynamic Wet Coefficient of Friction Testing
Hard surface flooring is generally more difficult to destroy than carpet, so you see it in many public spaces (e.g., airports, stores, hospitals, and schools). However, these various materials, including porcelain tile, have several disadvantages. The one that is important for this problem is that they tend to be more slippery than carpets. There is significant litigation around ‘slip and falls’ that are often related to someone falling in a public or commercial space. To reduce this liability for users of porcelain tile, manufacturers have put significant research into developing products that are less slippery. Around this work, several standardized tests have been developed to enable the comparison of products and the setting of safety levels. The standard you are working with tests dynamic wet conditions, where there is movement on a wet surface. Wet floors on which people are moving would be a situation with increased potential for slips and falls.

1: Complete the Statistical Calculation
Review and evaluate the problem presented – Using the tools learned in IDL 3 preliminary (attached) evaluate the problem: what you know, the significance of what you know to the problem, and what information you have that can be used in a statistical problem. Determine the appropriate hypothesis test to use, given what input you have, the problem, and the statistical tools you have learned. Additionally, determine the appropriate use of the null and alternative hypotheses for the problem. If it helps you can sketch a diagram of the problem.
read workshop 5 and 6 (attached)
Complete the calculation – Complete the statistical analysis of the problem. Be clear that you understand all of the processes you have completed to get your answer, you will have to document it.
2: Develop Your Document
Develop your document for the assigned audience and purpose – As you will have templates to use with many professional documents you will create, this assignment has a template that you must use memo template (attached).
