  1. Design a hypothetical Gauge R&R study complete with the purpose, people, proposed measures, actual measures (you can make these up or for extra points to a real R&R on something), and interpretation of results.

Expert Solution

Here we have taken a hypothetical example of a supplier of a product whose target= 43.1, Tolerance: +/-0.13 (0.26 total) and USL = 43.11 + .13 = 43.24, LSL = 43.11 - .13 = 42.98.

The supplier measured 10 samples of the product with three appriasers. Below data from excel shows that there is no part variation

By running frequency histogram, we will find that capability indices- Cp, Cpk, Pp, Ppk are good (as shown below)

By putting this data into QI Macros Gage R&R template we will get the following data:

NDC(Number of Distinct CategoriesIt) is a measurement of the variation in your sample parts. If it is less than 5, there isn't enough part variation to use the Average and Range Method to calculate Gage R&R.

Design a study to investigate the sylvatic cycle (wildlife cycle) of a hypothetical mosquito-borne virus. It is known that small mammals such as rodents are the reservoirs. Use critical thinking skills as well as the CDC and the journal Emerging Infectious Diseases to determine how to design this study. Include the hows/whys/wheres of sampling including sample sizes. Include the hows/whys/and types of testing (e.g., PCR or antibody or other, etc.). Address any pitfalls or expected results of your study.
