Suppose you use the weights 7, 1, 7, 1, 7, 1, 7, 1, 7, 1, 7, 1} instead of {3, 1, 3, 1, 3, 1,3, 1, 3, 1, 3, 1} in the UPC method. Do you think this altered method will detect single- digit errors? Either give several examples of numbers with an error that will not be
detected or explain why you think all such single-digit errors will be detected.
