A concept for a new microcomputer designed for use in the home is to be tested. Because a demonstration is required, a personal interview is necessary. Thus, it has been decided to bring a product demonstrator into the home. The city of Sacramento has been selected for the test. The metropolitan area map has been divided into a grid of 22,500 squares, 100 of which have been selected randomly. Interviewers have been sent out to call on homes within the selected square until five interviews are completed. Comment on the design. Would you make any changes?
