Your CMO wants to test the response to a new product that is designed to appeal to a subset of consumers - those that have lived in their current address for less than a year. She asks you to run a test and measure response based on a sample of 500 people. She suggests selecting the 500 consumers from the database in the following way: For each record, flip a coin. If the coin comes up Heads, then the consumer is included in the test. If Tails, then the consumer is not included. Is this a good way to assemble a sample to test response to the product? Why or why not?
