# Test the expert Part 1

 Report – Test the Expert Part 1 Instructions OVERVIEW Report Test the Expert documents an experiment that you design and perform, in which the ability of a test subject to identify 2 similar products among 20 samples served in a random order is evaluated. In week 5, you follow the instructions below. Between weeks 5 and 9, you begin updating the working report file, the design of the experiment is completed, and the experiment is conducted. In running the experiment, one-at-a-time, each of 20 samples is served in the random order determined in part 1 to the test subject, and identified by the test subject. In week 6 you learn how to use Excel file Statistics 250 to do statistical computations. In week 8 you learn the vocabulary and concepts involved with testing whether the test subject’s performance is good enough to discount guessing and be called an expert. In week 9, the ability of the test subject to identify the 2 similar products is evaluated statistically and the report is completed.

5.Using the chosen method and secret from the test subject, generate a list randomizing the order a total of 20 samples, about 10 of each of the 2 products, will be served.
