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 porcelain 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.
